Re: lights
You need to check all of the grounding at the lights. When the ground is bad, the current seeks a path to ground. If it finds one through another bulb, that's the way it goes and the light glows.

Re: lights
There is a ground wire on each light, most of which go into the harness and to a common ground connection either on the body or the block. The headlights usually have their own ground going to the body.

Re: lights
I had the same problem before, when I turned on the headlights the left blinker indicater would glow. It was the ground wire for the left front running light/blinker, it broke. I reconnected it and problem solved.
