I have a 1995 F 150 1/2 ton 4x4. 5.0 standard trans. Problem is the head lites after being on for 15 minutes or more start to flash off and on while driving.
New bulbs, new head lite switch in dash, new turn signal in column. All connections from what I have chased down and Ford here as well are fine, no idea why H/L flash like they do after being on for a short period of time, any idea as to what the heck is going on?

Truck does not have remore start nor did it ever, after market stereo years ago and thats it, nothing else is screwing up.

Thanks in advance to whomever can help me here.

Mark
