HID & LED Troubleshooting Guide

1. My HID Kit or LED Kit does not turn on at all.

If you install your HID kit or LED kit and they do not turn on you may have a reverse polarity issue. What this means is the power and ground wires of your vehicle's stock harness are reversed. What you will have to do is rotate the 2-pin oval connector on the ballast by 180 degrees in order to reverse the orientation of the plug.

This problem is unrelated to the HID kit or LED Kit. It is an issue with the vehicle's factory wiring orientation. Halogen bulbs are not affected by polarity therefore some car manufacturer may have their polarity reversed.

If your HID kit or LED kit still doesn't light up after reversing the polarity, your headlight fuse might be too weak. Upping the fuse by 5 amp might do the trick.

2. My HID Bi-Xenon high beams or low beams are not working or are inverted.

This is a similar issue as above, the polarity of the connector's pins are not correctly aligned. Bi-Xenon HID kits have 3 pins on the harness connector for ground, low beam and high beam connections. You will need to release the pins inside the connector and reorder them. You may need several tries to find the proper orientation. Look inside the connector and with a precision screwdriver you can release the pins and reverse the wires.

3. My HID lights are flickering.

Flickering usually means the car is unable to supply enough power to the ballast. You can easily test this by connecting the HID kit directly to the car battery. If the kit works, it is a power issue. To resolve this you will need a wiring harness.

If your car has Daytime Running Lights (DRL) flickering is usually caused by the lower voltage needed to run the DRL at half power. The car's factory harness does not provide enough power to the ballasts. If the flickering is caused by the DRL you will need a wiring harness or have the DRL disabled (this may not be legal in all areas).

Flickering can also be caused by the vehicle's onboard computer failing self-check test due to the new HID kit you just installed. This can easily be corrected with a set of warning cancellers (capacitors).

4. My LED headlights are flickering.

LED lights may flicker on some vehicles, this is caused by the vehicle's onboard computer failing self-check test due to the new LED kit you just installed. This can easily be corrected by adding a set of warning cancellers (capacitors) to your setup.

5. My HID kit works sporadically.

If only one side turns on from time to time or you lights work inconsistently, you probably have a power issue. You will need a wiring harness to power your HID kit directly from the car's battery.

If you install the wiring harness and still experience intermittent firing, please check your wiring connections. Make sure the power terminal is properly connected to your car battery and that the wiring harness is securely grounded.

6. Only one side is working on my HID kit or LED kit.

If one side sometimes doesn't turn on it could be caused by a bad bulb, HID ballast, LED driver or wiring. To help identify which component is defective follow these steps.

  1. Swap the ignitors to opposing sides (not applicable for LED kits). If the problem is reversed you might have a bad ignitor.
    • This step will check if you have a bad ignitor. The ignitor is the black rectangular box that is plugged between the ballast and the bulbs. To perform this test, please swap your ignitors to opposing sides and note what happens to your kit.
  2. Swap the HID ballasts or LED drivers to opposing sides. If the problem is reversed you might have a bad ballast.
    • This step will check if you have a bad HID ballast or LED driver. The HID ballasts or LED drivers are the two metal boxes that came with your kit. To perform this test, please swap your HID ballast or LED driver to opposing sides and note what happens to your kit.
  3. Swap the HID or LED bulbs to opposing sides. If the problem is reversed you might have a bad bulb.
    • This step will check if you have a bad bulb. To perform this test, please swap your bulbs to opposing sides and note what happens to your kit.
  4. If none of the above helps, please check for loose connections. If you installed a power relay harness with your HID kit, make sure you have properly grounded the harness.
