At night when the highbeams have been on for about 20 or so minutes they flash on and off along with blue indicator high beam light. Strange enough the problem doesnt effect its ability to return to low beam at all and I havent experienced any problems from low beam. Why is this happening.

 

If I'm wrong someone correct me. I think there is a circuit breaker built in the headlight switch and some times they get weak and cause that. I know the older model vehicles had that.
