ok so my headlights started to act kinda crazy tonight. Problem is, when my low beams are on....only the passenger side works. When the high beams are on.....the passenger highbeam comes on and the drivers side low beam comes on...but high beam does not. Any ideas??

 

Sounds like a bad ground to me on the drivers side. Korey

 

Check the wiring harness/grounds. Mine does that, if I jump out and jiggle the harness it comes back on.

 

but if its a bad ground why would the lowbeam come on when i turn on the highbeam?

 

Check the fuses and relays for the lights, sometimes a burnt fuse can set off that problem...

 

Looking at your profile photo it looks like these are not factory lights you are dealing with. Make sure all the grounds, wires and connections are tight. If you have the factory lights put them back in and that will tell you if it really is a wiring issue or a aftermarket headlight issue...

 

The actual wiring has nothing to do with the housings, with the possible exception of the halo...

The bulbs don't use the housing as a ground or anything like that...

The lights will work perfectly fine just dangling in the air, if the wiring is in good shape...

I'm pretty sure it's a fuse or relay issue, though, but it wouldn't hurt to go out and wiggle the wires on the back of the bulb and see what happens...

What's the wattage rating on the projector bulbs?

 

The low beam coming on when the high beams are could be because the ground is bad and it is finding a ground through the low beam bulb. I have seen this happen allot of times,grounds are very important things, that is for sure. Korey.
