I have a bi-xenon kit installed and for a couple of weeks they worked great. I had to tap into the parking light harness to get them to stop strobing. Anyways, I went out to work this morning, unlocked my truck and the lights were on. Not the parking lights, just the lights. I cant get them to turn off. The truck started up fine, so I doubt they were on all night. What could be the problem?

 

maybe whenever you unlocked the truck thats whenever they turn on

 

I think the relay is sticking which doesnt allow it to close.
