Why is my LED light bar not working?
Unplug the light from the harness and connect to the vehicle’s battery or power supply with similar voltage. If the light has fired up as it should the problem will be in the wiring, proceed to the next step; Make sure that the switch is still receiving power (will illuminate once switched to the on position).
How do I know if my light bar relay is bad?
Since the light bar relay contains a mechanical switch that completes the circuit you can place your finger on top of the relay and then press the light bar switch on and off. If the light bar relay is working, you should feel and possibly hear the switch inside the light bar relay complete the circuit.
How can you tell if an LED bulb is blown?
2 Answers. It’s an LED. Easiest way to see if it is damaged is to connect it to a battery and see if it lights up. The difficulty is that you can’t disassemble the the white plastic unit, so if the LED does not light, the connection wires, resistor or LED itself may be damaged.
How do I know if my LED driver is bad?
Still Having Issues, Use a Multimeter?
- 1.) Test the AC Input with a Voltage Multimeter.
- 2.) Apply your test leads to AC Power Source.
- 3.) Check AC Voltage Reading on Multimeter.
- 4.) Set Power Supply to Proper Input Voltage Setting.
- 5.) Measure the Output DC Voltage.
- 6.) Apply your test leads to DC Power Source.
How do you fix a flickering LED light bar?
Summary – How to stop LEDs flickering
- Always drive LED products using an LED power supply that’s designed for the job.
- Make sure all your LED products are compatible with the control circuits and power supply you’re using.
- Check for loose wiring and other faulty connections.
- Consider using a constant-current LED driver.

What do you do if your LED lights wont turn on?
If the LEDs will not light up at all, then this could be down to a faulty power supply. Solution: If you have several power supplies, then try a different power supply onto the same strip to see if this now works. If it does, then you have a faulty power supply and will need a new one.
Do LED light bars need a relay?
A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. … If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.
Why do LED lights have 3 wires?
LED Lights with 3 wires will be a multi-function light. They can (most times) be used in whatever configuration is right for your application. For example, running and brake, running and blinker or brake and blinker. These LED’s will usually have a black, red and white wire.
How do you know if a light bar is good?
Ingress rating or IP rating separates the good light bars from the bad ones. For instance, the Aurora LED light bars have an IP69 rating. The number six means the product is sealed and protected from dust entering the LED light.
What happens when LED lights burn out?
Details. Unless an actual component in the LED fails, they will provide light “forever.” While LEDs do not burn out like fluorescent lamps and other bulbs they will, however, degrade and dim over time. The diode itself will begin to emit less and less light as the years pass. Still, LED lamps can last over 25,000 hours …
Do LED bulbs flicker before they burn out?
LEDs only provide light when an electrical voltage runs through them. If this voltage is not constant, flickering will happen. This only affects LED bulbs because others like halogens and incandescent maintain enough heat to cover brief gaps in voltage. LEDs don’t.
How long should a LED light bulb last?
Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years.
