LED Headlight Bulb Troubleshooting Guide
|Do Not Turn On When Install||1. Check if the power connectors are properly connected, and make sure that the vehicle headlight switch is in the “ON” position.|
2. Make sure that the vehicle’s battery is fully charged to supply power to the LED bulb.
3. Some bulb sizes (like H1, H3, H7, H11, 9005, 9006, 9012, etc.) are polarity sensitive. If the LED bulbs do not function properly after installation, please reverse the plug male connector 180 degrees and try again.
|LED Bulbs Are Flickering When Install||Install the LED bulb with an Anti-Flicker capacitor/resistor.|
|DRLs is Flickering||High beam and DRL are sharing the same bulbs and DRLs work with lower power. Change light settings from automatic to manual or disable DRLs.|
|Dashboard Warning Lamp||This is a harmless side-effect of the low-wattage LED bulbs not being recognized by the vehicle’s system and can be resolved with the installation of an additional set of resistors (CANbus).|
|Bad Light Pattern/Glare||Check whether the bulb is rotated in the correct direction and locked in place.|
The LED chips should face 3-9 o’clock and the wire harness should be down to 6 o’clock.
Please follow the Installation Guide above to adjust.
|Flickering Suddenly After Working For A While||1. Check if the battery is sufficient, otherwise, replace it with a new battery.|
2. Replace the dust cover with more space for heat dissipation.
|Dust Cover Can Not Be Installed Back||Some rubber dust cover does not have space for the wiring of the LED bulbs so you may need to do a little modification. Drill a hole in the cover, get the wire from the LED bulb outside of the headlight assembly, then seal the hole well to ensure the bulbs stay water and dustproof. A larger dust cover is better.|
|The LED Bulbs Are Loose And Cannot Be Fixed||Please forcefully push the LED bulbs into the light housing and then rotate it clockwise. Please note that the chips need to face left and right.|
|Bulb Not Working/Burn Out/Turn Dim||1. Make sure the connection is good.|
2. Swap the LED bulbs to the other side. If the problem is still, you probably have a bad bulb.
