LED & HID Troubleshooting Guide

1. LED / HID Headlights Do Not Turn On

This simply means the power and ground wires are reversed in your vehicle's harness. Halogen bulbs are not polatiry sensitive, hence manufacturers may reverse them sometimes. Rest assured, it is not an issue with your LED / HID headlights.

LED: Unplug the connector, rotate 180 degrees, replug connector.

HID: Unplug the connector, rotate the 2-pin connector 180 degrees, replug connector.

If you are still having issues with your kit not lighting up, increase the amp output by 5 amps on your fuse.

2. LED / HID Headlights Are Flickering

Headlight flickering is usually caused by the on-board computer not recognizing the newly installed led or HID headlights. This is fixed by using warning cancellers / capacitors. For HID headlights, it can also mean you are not getting enough power to the lights.

LED: You can easily fix this by adding a set of warning cancellers / capacitors.

HID: Test the power to the lights by connecting the HID headlights directly to the vehicle's battery. If the headlights work, it is a power draw issue. You will need a power relay harness to fix this.

On HID headlights, if power draw is not the issue, you will require a set of warning cancellers / capacitors to fix this.

3. LED / HID Headlights, Only One Side Working

When only one side does not turn on, it's usually caused by one of the components not working as it should. To help identify the broken part, you can follow these steps.

BALLASTS / DRIVERS: Swap the LED drivers or HID ballasts to the other side. If the problem is now reversed, you probably have a bad ballast.

BULBS: Swap the LED / HID bulbs to the other side. If the problem is now reversed, you probably have a bad bulb.

IGNITORS (HID Only): Swap the ignitors to the other side. If the problem is now reversed, you probably have a bad ignitor. The ignitor is the box plugged in between your ballasts and bulbs.

If none of these steps help, please check your setup for loose connections. If your vehicle has a power relay harness (HID Only), check to make sure the harness is grounded.

4. HID Headlights - Intermittent On/Off

If you are experiencing your HID headlights working sporadically, you most likely have a power draw issue. You will need to install a power relay harness to fix the issue. Connect it directly to your vehicle's battery.

Always make sure your power relay harness is properly grounded.

5. HID Bi-Xenons Not Working or Inverted

If your low or high beam on your HID bi-xenon headlights are not working or inverted, it is most probably an issue with the polarity.

Make sure the connector's pins are properly aligned. You should have 3 pins on the harness (ground, low and high beam). Release the pins and reorder them in order for the connector pins to align. This process may be repeated until you find proper orientation for the pins.

Always make sure your power relay harness is properly grounded.
