Several different reasons will cause that your lights won't work properly.
If the lights stop working completely
There is a simple way to determine whether the light is faulty, that is to connect the light to a 12v DC power supply directly. Remove the light from the harness and connect it to the vehicle's battery or to a power source with a similar voltage. If the light is on, there should be a fault with the line. Go to the next step.
Make sure the switch is still energized
Check any loose connections through the wiring harness to make sure nothing is loose.
Check that the ground/floor is still safe and properly installed.
If the light is not lit from a direct power supply, the problem is with your light.
Possible reasons for the partial working of the light bar
Poor grounding is usually the main cause of partial lighting. The best way to test whether there is defect in grounding is to change chassis grounding to battery negative terminal. It is wrong by checking the voltage of the light connector to determine whether it is improperly grounded. Maybe it is 14V + at the light connection, but the light still has bad grounding. That eventually leads to a difference in input power.
Check the voltage of your vehicle's battery: Generally, this can be caused by low voltage. Lower than what the light bar required will reduce the brightness of the light bar, or you will see alternating patterns of LEDs. This can sometimes be solved by recharging or replacing the battery. Double check whether all wiring is properly connected in order to ensure there is no weak spot in the wiring.
Why is my LED light bar flashing?
If the sampling resistance increases, the light will darken or remain inactive, so the output voltage is very important. When current sampling, the resistor power must have a margin.Where to mount LED light bar?
The light bar is mainly installed on the top of the car, the front and middle of the vehicle, or the position of the bumper. Using the existing hole, the front bumper is the easiest place to install the light bar. If you want to install smaller LED work lights, they usually come in pairs, either on the car's front safety bracket or in front of the rearview mirror.
They are generally mounted on the roof of 3-4 rows, if there is a roof rack, they can also be mounted on the roof rack.
Can LED light bars be mounted upside down?
The light bars can be mounted upside down by mounting them on the top of the plastic bumper. The space there is completely open. When the bracket is flipped upside down, the light bar sits right between the top of the bumper and the license plate rack.
How long do LED light bars last?
According to the U.S. Department of Energy, quality LED lights should last 30,000 to 50,000 hours, some even longer. Some bulbs burn for 50,000 hours, while others don't, which depends on several factors, including the type of light fixture and operating temperature.
When used outdoors, LED lights won’t be affected by low temperatures. However, they will be affected by heat.
The radiator is placed at the bottom of the LED bulb to take the heat away, but when you have a closed housing, the heat has nowhere to go but back into the bulb. If you plan to use enclosed light fixtures, you’d better to look for LED bulbs designed for such housings.
The first white LED lights hit the market in the mid-90s, and since then huge improvements have been made to improve the efficiency and service life of the original design. The average life span is 30,000 to 50,000 hours, but some can last up to 100,000 hours.
How long will light bar last on battery?
If your car has a built-in 2000mAh large capacity rechargeable lithium battery, charged via USB 5V plug charger, portable power pack or computer, when fully charged, it can be illuminated for about 50 hours in minimum mode, 12 hours in medium mode, and 4-5 hours in maximum mode.
How to test LED light bar with battery?
The first step is to make sure that the battery could provide enough power to the light bar, otherwise the light bar may not turn on.
You can test your battery with a multimeter to make sure your battery has 12 volts when not working and 14 volts when working.
Battery connection: Loose battery connections can limit the power of the vehicle and light bar. Any battery terminals that can be rotated by hand should be tightened in accordance with the vehicle manufacturer's specifications.
The second step is to check the wire-harness of LED light bar
Light bar power and grounding: Find the power and grounding connections for the light bar and make sure they are securely connected and free of corrosion.
Light bar fuse: If you have a LED bar, it will be equipped with a waterproof built-in fuse. Open the fuse holder cover and remove the fuse. Point the fuse of light bars at the light source and check the metal EMI gasket to make sure it is not blown. If you determine that the fuse is damaged, replace it with a fuse with the same rating for the light bar.
Check relays: All light bars have 12 volt relays and some have 24 volt relays.
The easiest way to test a relay is to replace it with another relay that works. If you have a backup light bar relay, then use it to see if the problem is solved, and if you are sure the light bar still doesn't work, proceed to the next step. Because the relay of light bars contains a mechanical switch that completes the circuit, you can place your finger on top of the relay and press the switch of light bars. If the relay is working, you could hear that the switch in the relay connect the circuit.
When LED light bars make noise
After installing the light, the noise may be caused by the light, or it may be caused by driving too fast
1. The radio is disturbed and produces noise, which is generally caused by wireless interference.
Solution: Buy ferrite clips. Ferrite clips can repair radio interference.
2.The sound of the light bar is very loud in the process of driving.
This is because in the process of driving, the wind enters the bottom of the light bar and touches the radiator of the light bar, making it sound like a musical instrument.
The solution: Buy a baseboard, cut it to the right length and size, and make a diffuser that changes the direction of the wind so it goes up and doesn't wind around the light bar and make noise.
When LED lights were invented?
As early as 1907, people found that some diodes made of semiconductor materials have the physical phenomenon of shining when positive conduction, but it has been 1969 for the production of red LED with a certain luminous efficiency.
Blue LEDs were developed in 1994-1995 and commercialized in 1998. From 2000 to 2002, LED successfully entered the mobile phone backlight market under the continuous pursuit of cost effectiveness by the R&D personnel.
Today, LED has been produced for more than 30 years, various types of LED, products secondary developped based on LED and products matched with LED (such as white LED driver) develops rapidly, new products come into the market continuously, and has developed into a new industry.
Regarding LED technology research and development, the story most talked about is the contention between silicon carbide (SiC) and gallium nitride (GaN) when developing blue LED.
Following the breakthrough of blue LED technology, white LED officially started a wide LED application range. From display, indicator and mobile phone light source to the brewing LC-TV backlight source, the door of various new opportunities have been constantly knocked open by creativity. LED is a semiconductor device developed from the three fifth group (III-V group) compound semiconductor after silicon (Si) semiconductor technology in the 1950s.
The principle of lighting for LED is combining electrons and holes in semiconductors to give out photons, different from the light bulb which needs to operate at high temperature above 3000 degrees, also not like fluorescent lamp which uses high voltage to motivate electron beam, LED are the same as general electronic components, only require 2-4V voltage, can operate normally at room temperature, Therefore, its life span is longer than traditional light sources.
The color of the LED is mainly determined by the amount of energy released by the combination of electrons and holes, that is determined by the energy gap of the semiconductor material used.
The wavelength is very similar for te same kind of material , so the light color of each LED is very pure. Compared with the traditional light source, which is mixed with many colors, the LED can be said to be a digital light source. LED chip size can be cut randomly for the purpose, the commonly used size of 0.3-1.0mm or so, compared with the traditional bulb or fluorescent lamp, the volume is relatively small.
When LED bulbs flicker
1.Zero line charged
This is a common situation. ① When the plumber wires, the alive circuit enters the LED bulb holder directly, and the zero line enters the control switch. Although the switch is off, there is still a current in a live wire.
When the light reaches the switch, it still lights up slightly. Solution: In this case, adjust the wiring so that the switch controls the live wire.
The switch controls the zero line to make the current flow through the lamp.
② The plumber connected the wrong line when entering the main gate and the fire-fighting zero line was connected reversely, hence all the fire-fighting zero lines were reversed accidentally, resulting in all the switches controlling the zero line. The solution in this case is to adjust the incoming line only.
③ If the switch controls the live line, use the traditional mechanical wall switch, or the switch shines, then the zero line is charged. Zero line charged is a very common phenomenon. If the grounding of zero line is not good, three-phase load of transformer is unbalanced, the line is too long, the line diameter is too fine, or the current of zero line is too large, it will charge the zero line.
Solution:Re-ground the zero lineor perform low-voltage conversion.
(This requires professionals for operation)
2.The dual control switch is connectedincorrectly.
Wrong connection, though can also be used
There are several wiring modes for dual control switches. If the wrong connection is used, traditional incandescent bulbs will not light up, but LED lights will light up slightly when turned off due to direct current. The solution to this situation is to install the normal control live wiring method and rewire.
Properly connected, any switch can cut off the power
The wiring mode for double control switches: single link double control switches, three contacts on the back, namely L, L1, L2. Firstly, connect two L1 and L2, connect the live wire to the L contact of a double control switch, and connect the control loop wire to the L contact of another double control switch.
3.Switches are equipped with indicator lights, using electronic and touch switches
There is an indicator light inside the switch.
When the lights are off, there will be a weak current.
If the lamp uses electronic touch switch, such as infrared, voice control and remote switches. There is also a dim light when the lights are off. The solution to this situation is: ① Replace the switch. (2) the 500K resistor should be connected in parallel at the inlet of the lamp. However, professional and technical personnel should measure and install this method, while non-professional personnel should not operate at will. In addition, this method is not effective for low luminescence caused by the zero line charged or patch leakage.
4.Leakage of unisolated drivers, light source patches and substrates
Taking account of cost, many lamps adopt low quality resistance-capacitance to drive step-down, or the light source patch is of poor quality, and there is leakage between the patch and the substrate. The copper plating and capacitance effect for substrate can also lead to light leakage. Solution: Replace the lights.
Although your UTV comes with decent lighting to serve you during night trips, investing in an aftermarket light bar is a great decision to improve your machine’s lighting. Installing a light bar means more lumens to brighten your way and see more of the road ahead when the sun is out of sight.
However, while installing a LED light bar on a UTV is something you can do on your own, not every UTV owner knows the required process for installing the bar on their quads. Hence, it is important to find the right guide for the task.
Here is a detailed guide to walk you through how to install a light bar on your UTV:
The first step to installing a light bar on a UTV is to disconnect the energy source. Installing a light bar on your vehicle draws from the available energy source, draining it faster than you might think.
Since your UTV’s energy source is the battery, disconnect the battery.
Start by disconnecting the negative terminal before moving on to the positive terminal. This will help prevent the risk of a short circuit during connection.
The next step is to look for a good position on the UTV to mount your light bar. Although you have several options when looking for a good place to mount your light, choose somewhere where the light can function most effectively.
The front bumper is a good place for most UTVs, especially for convenience. Also, mounting your LED light bar on the front bumper ensures no obstruction blocking the light from illuminating your path.
Regardless of your ideal position to mount the bar, fit your light using the provided installation hardware in your light pack. You can also invest in optional round tube brackets for your light installation.
While fitting the light, be careful not to tighten the bolts completely, as you will still need to adjust later.
Your UTV light bar requires electrical power to function, and the requirement is usually 12 volts.
Hence, it is important to look for where to get this supply. Fortunately, you can easily get this power supply from your UTV with no hassle. The common and easiest way is to cut two wires supplying power to one of the existing headlights and connect your new light bar.
Connecting your light bar to a power source requires a harness that must be properly secured. Securing the wiring ensures it is kept away from moving parts and heat. Failure to secure the wiring lets it rub against metal parts, leading to a short circuit. Finding an existing wiring path in your UTV is best to run the new wiring.
A relay is an electromechanical device that turns a large electrical circuit on and off with a small electric current. Besides switching electrical loads on and off, a relay's major advantage is energy preservation, ensuring that your light bar doesn’t draw much energy from your battery. This helps extend your battery and device life.
For example, a light bar installation without a relay would result in a huge voltage drop from the battery to the light, generating a lot of heat due to the resistance.
Hence, you want to introduce a relay to your installation.
However, this doesn’t stop you from installing a control switch. A control switch is integral to the installation and gives you full control of your light bar.
Once you are through installing the LED light bar on your UTV, it is time to reconnect your battery. Start by connecting the positive terminal, then the negative terminal.
Now, it is time to test your installation. Turn on your switch and watch your new bright light illuminate. If your light comes on, pat yourself on the back, as you have successfully installed a light bar on your UTV.
But wait, you are not yet through with the installation. Remember that you haven’t fully tightened your hardware. Complete the UTV light bar installation by tightening the hardware completely.

Please note that nothing is displayed on MZSA trailers for the 5th signal. Accordingly, if your side lights are not on on your MZSA trailer, most likely the signal is output to the towbar socket only on the 5th contact, but not on the 7th.
Some Russian trailer manufacturers, when installing a reversing light, connect it to the 5th terminal, and leave the 7th contact behind the dimensions.
For a long and trouble-free service of the electrical outlet, we recommend that after connecting the contacts, coat them with lithol or grease, and securely treat the place where the wiring harness enters the outlet with sealant.
The wiring diagram for the 13-pin trailer socket is discussed in a separate article.

A car battery is one of the most unreliable elements in a car's design. It is enough to forget to turn off the dipped beam, leaving the car in the parking lot for the night, so that the amount of charge drops to the minimum values that are insufficient to start the engine.
Battery discharge accelerates at sub-zero temperatures, so the problem is relevant for drivers who do not have their own warm garage.
If the battery is left half-discharged for a long time, its capacity and service life will be reduced. For infrequent trips, auto mechanics recommend regularly recharging from portable or stationary devices. But if the problem happened suddenly, and you need to go, you can’t do without a starting device.
It is necessary to distinguish between the functionality of starting devices and chargers. The first group allows you to start the engine regardless of the battery charge, the second one replenishes the battery condition, but does not give a starting impulse. Combined starter-chargers have a wide range of capabilities, but their use requires increased attention from the owner: an incorrectly set mode can damage the battery.

Compactness
Low battery capacity, No safety features
The trigger is a simple device, but the devil, as you know, is in the details. Andrey Tabolin, R&D specialist at Artway Electronics , told Komsomolskaya Pravda about the details that must be known and taken into account when choosing starting devices.
When choosing a starter charger, first of all, you should pay attention to the following three parameters:
1. Engine size and fuel type of your car
2. Starting current.
3. Output voltage
Normally, the specifications for a car battery indicate the starting current.
But it is usually higher than required to start the engine. For example, on a car with a 1.6-liter gasoline engine, a battery with a starting current of 500A can be installed. But in fact, 200-300A is required. Diesel engines with the same displacement require more starting current. In general, the larger the engine size, the higher the starting current the device will have to produce.
The voltage of the on-board network in most cars is 12 volts. It is this voltage that ROM should give out, with which it is planned to start the engine of a “passenger car” in cold weather.
Along with these important parameters, we also advise you to pay attention to the capacity of the built-in battery, the level of charging current and additional features of the device, for example, the presence of control devices, a charge indicator, a flashlight and other useful functions.
Starter chargers suitable for all batteries.
And in order to insure yourself against the problem of a dead battery, experts strongly recommend purchasing start-up chargers in advance. They will be especially relevant during the cold season.
Specific terms for replacing a car battery depend on the conditions in which it was used. With proper maintenance and under gentle working conditions, the battery can last up to 6 years. But, as a rule, the frequency of its replacement is 3-4 years.
We advise you not to take the situation to the extreme, and not to wait until it finally "dies", but to attend to its replacement in advance. The condition of your battery can be checked at a car service. You can also determine the incorrect operation of the battery yourself, focusing on the following indicators:
1. Difficulty starting the engine, especially in cold weather;
2. Flickering or dimming of lights and bulbs;
3. Mechanical damage to the battery case;
