My headlights wont come on sometimes, and when they do I will be driving and they just go out. Sometimes when I step on the break they go out. I put the window down they went out. I can flip them up and down sometimes it turns back on sometimes not. The high beams always work so I just flip them on when they go out?

I replaced mine with a later model lkm that has chips instead of relays. Check for them online on ebay etc. Ive had no more problems since.
