I dont know if it has anything to do with my subs, it shouldnt, but sometimes my right headlight will GO OUT, not dim, but go out and then come back on like a few seconds later. It only happens on low beam and on high I havent seen it happen. Any suggestions on what could be the source?

Deffinitly check all the wires connecting the headlight. It cant be the fuse. And if its only one headlight, has to be wires somewhere, a short. See what happens if you run the car with out the fuse to the subs one day at night 2 see if problem still happens just incase.

Maybe your low beam bulb is going. Try swapping both low beam bulbs with each other and see if that bulb does it on the other side. If it does, then u should replace it. If not and the other bulb starts acting up on the same side, then it's your wiring.

Thanks ill check the harness. I just replaced the bulbs like 2 weeks ago so I dont think its that.

By chance, do you have projector headlights? I have noticed that with some projecters the wiring/connectors kind of seems to come loose go bad, realy not sure, but the light will go out, and when you kinda smack the housing from the backsideit comes back on...I don't know if you have projecters. but if you do, thats a thought as to what it might be.

I definatly think it's something in the wiring though. It only does it on right side, so swap the bulb from the left side in. If it does it with that bulb, you can pretty much figure it's the wiring and/or connector. Just reading the post though, I am guessing it's wiring. If you have projectors, that more than likly it, especially if it's they're Sonar (gen 3 is a sonar brand) projectors. I hear of all sorts of problems all the time with that brand.

I hope this was of some sort of help to you.
