Headlights

[Crusin]

I have noticed recently that when I start my ZR-1, the left front headlight pops up after driving for maybe 30 seconds then it goes down. I seldom drive at night but when I did last week, after starting the car only the left headlight came up, turned the car off and started it again and both headlights came up. A night or two later only the left headlight came up.
I turned the car off and just turning the headlight switch both headlights came up. The next morning just turning on the headlight switch both headlights came up again, I tried it at least three times and every time both headlights popped up. Later that day I tried the same thing again but this time the right headlight didn't pop up. I was wondering if this could be a electrical problem. This season is starting out like a season from hell. I would appreciate any advice in regards to this issue. Thank You
