my 91 tbird is having a weird headlight problem. After about 20 minutes of driving when the car is fully warmed up, the headlights, and only the headlights, start turning themselves on and off. At first i thought it might be the battery, and though the battery was almost dead, replacing it hasnt improved the condition. My brights still work, and unfortunatley ive had to **** off my whole city on the drive home every night. I pulled out my dimmer switch (one of the **** kinds that you pull out to turn on the headlights) and took a look at it. It looks badly worn, and was very hot to the touch. Could this be the cause of my problems?

 

I beleive there is TechServiceBulliten about this. Something about the breaker needed to be changed from a 18A to a 25A.
