Hi, I'm new to the forum, and have a question. I was installing an h11 35w hid kit the other day on my friends 2007 Sierra and now nothing with the lowbeams will work. Initially I had one side working (passenger) but was doing some trial and error and now both sides don't work. Tried going back to stock bulbs after it got too dark to continue the project, but they won't ignite anymore either.

I feel terrible as this isn't even my truck, but am astounded as I have installed dozens of hid kits previously in other vehicles.

I've checked the 31,33 and 34 fuses but all are still intact. I'm hoping it's just something silly that I overlooked but it's been a couple days and he's getting tired of driving with no headlights.

Any help would be great thanks,
