HID Relay Harness
Base Price: $19.95
Why do I need a relay harness?
Some vehicles might be able to power up HID conversions normally without problems at install time. It will probably not last long. The inrush load can be up to max 13 amps per ballast, compared to 7amps inrush when using halogen. The factory design parameters for headlight circuits are 7 amps inrush and 4.5 amps continuous load. So over time, connectors, multifunction switch, headlight switch, wiring and fuse holders will slowly degrade, because of heat buildup. These components are very time consuming to troubleshoot because they are usually well hidden behind dashboards and other wiring looms. Parts can cost several hundred dollars and add up to 8 hours of labor to that and it becomes obvious that relay wiring harness is a cheap insurance.

Questions:
When I start my car with the HID kit turned on, why do one or both of the lights turn off.
The lack of power and pulsing voltage when your starter is cranking may activate the safety circuit in the ballast and turn one or both off to protect itself.
Solution:
You may either start your car with your headlights turned off, or install the "autolamp / daytime running lights" relay harness.
How do I know if I need a "autolamp / daytime running lights" relay harness?
- If your car has headlights that turn on automatically when it gets dark then yes you may require a harness.
- If your DRL circuit shares with your low beam it may only output 50% - 80% power when your DRL is active and will cause your lights to flicker. That lack of power is not enough power to activate the HID ballast thus requiring a autolamp/DRL relay harness. In some vehicles you can remove the DRL relay or fuse to disable your DRL. This will stop your lights from flickering when you start your car. If you are able to disable your DRL then you will not need a autolamp/DRL harness as well.
- If you have a BMW that has a headlamp sensing system you will require a BMW harness.
If your vehicle is running at 100% operating condition you may not need a relay, however, if your electrical system does not output 12 volts consistantly you will need a relay.
