So I recently bought a subwoofer for my 2002 tl-type s and hooked it up this weekend. I did the whole grounding and remote power wiring set up and everything seemed to work fine. After riding around enjoying my additional bass for a few hours I went to turn on my lights and I noticed that my Driver side headlight is not working. These are hid lights and don't just go out for no reason. Does anyone know what could have caused this ? I just do want to run out and spend 100$ for a new light, Thats a lot of money for a broke college student such as myself. Any help will be much appreciated thanks for anything you contribute.

 

Hey Cmt2431, could've been coincidental.......anyways, if ya wanna check the driver's side, then the easiest and cheapest way would simply be to swap the known good passenger side lamp with the driver's side.
You'll then know if it's a bad bulb, but if the swap fails then you may have other problems with the HID components or wiring.
