How would a bad headlight switch intermittently activate the battery and brake dash warning lights? headlights work just fine.
I have read that there is a relay mounted behind the glove box that somehow activated the battery and brake warning lights and when it goes bad they can come on intermittently.
Hahahaha, my bad, that's what I get for skimming. Was just reading you saying lights over and over and assumed headlights lol.
I'd definitely check that relay you're talking about though, sounds more like a relay than a charge issue.
