Any clue as to why the driver's side headlamp on a 94 LS would alternate from dim to bright? Sometimes I'll be driving and its noticeably dimmer than the passenger headlamp, and other times they are equally as bright.

Possibly a bad connection in the lamp socket, corrosion on the contacts, a bad or loose chassis-ground connection etc. It's also remotely possible the bulb itself is goofy.
