Help! Headlights won't turn off!

[Fauxnali]

So, I've had my Yukon for a year now and it came with a set of HID's (don't have the stock ones) and I've never had a problem but this morning I walk into my garage and the headlights are on. No other lights just the headlights. I washed the truck yesterday but other than that nothings been done to it for a while now. I unplugged all fuses and relays from the fuse panel to no avail. The lights would not go out until the battery was undone and when I hooked the battery back up only the left one came back on. Any thoughts?

So, I left the battery unhooked for about a half an hour and then reattached it. Things are now working fine. Dam electrical gremlins.

Very strange, hopefully unhooking the battery fixed it for good

A day later and still so far so good.

I just installed HID in my 07 Yukon XL Denali and used the hi/lo relay harness. It is directly attached to the battery with its own fuse. This maybe why you could not find a fuse that disabled it.
