Posted this in the 2009 forum too, but figured this couldn't hurt. Last year I installed a set of the new HID's in my 2012 with the wiring harness for sale on the forum, just tonight they've started giving me issues. I noticed that first they would spaz when I locked the truck, and now they won't turn off. Even if the light switch is in manual off, they're on until the battery is disconnected. Any ideas? I'm thinking either the DRL module or the relay in the wiring harness I had to put in, but am by no means an expert.

Thanks!

 

unhook the trigger wire from the high or low beams to the relay... if the lights go out then the relay works... it could be the relay stuck... they are cheap and available anywhere

 

Just an update for anyone who has a similar problem, the morimoto box on the aftermarket wiring harness fried itself at some point. Everything on the factory side is good to go!

 

I'm sure TRS will get you sorted out.
