65 Vette - Headlight problems
 

I have a 1965 Corvette - 365 all original transistor ignition.

My problem is my headlights flicker on and off after being driven for about 45 minutes to an hour. Once they start flickering they don't stop.

I have checked connections at the fuse panel, light switch, headlight motor switch - nothing wrong.

The manual says that I have a 15 AMP circuit breaker; however, I can not find it. Any help?
