About 10 months ago I installed HID low beam headlights on my '04 Trailblazer. All was well and good until tonight (of course I'm taking the car away for vacation TOMORROW!!) when both low beam lights went out. They didn't blow out when driving meaning they both blew as soon as they were powered on as I never saw them blow. I didn't think it was the fuse because they are on seperate fuses. I tried them anyway and it's not the fuses.I think I would have noticed if one blew out earlier (and the other just blew) but I can't be sure. Anyone have any idea's or experiences similar or better yet, a known fix? Thanks for your input.

my understanding is that the relay takes the one that is getting power from the truck and powers the other, so if there is a problem with one, the other will die as well. do you run with drls? do you ever have to manually kill them during the day because one or the other powers up on its own?

My DRLs were disabled using the kit I bought by one of the Trailvoy members. So are you saying that the problem is with the HIDs or will I have the same problem if I put in my halogen bulbs?

were you using a relay? there should be a fuse in the relay check to make sure that fuse is not blown; also they shouldn't be but just double check the 2 fuses for the lights under the hood

I am using a relay but i don't remember of there is a fuse in it. It's a pain in the butt getting to it because I have to remove the middle seat. I already checked the fuse under the hood and that wasn't the problem.

you have to remove your middle seat? how do you have everything hooked up; the relay should be hooked to power under the hood; either the battery or the post infront of the fuse box? mine has a fuse near where it attaches to the post for power on the red wire:undecided

edit; oh you are reffering to your DRL killer; no i am talking about a relay powering your ballists; are you using a relay harness there?

I don't know how you've wired your HID's. However with regular headlights there are separate fuses for each side and one relay (#46) that covers both headlights. Try swapping #46 and #45 (fan relay). If the lights work you just need a new relay.:m2:
