Not the tail or side markers just the fenders. What the heck could cause this? There is also a switch in the dash that says blink marker or something it is a factory switch what is it suppose to do? thanks Jake [Reply]  [No Email]

Truckers do that as a courtesy when being passed by another truck to let them know that they are clear to get back over after passing. And yes, it is a factory switch.   [Reply]  [No Email]

The other switch is an early attempt at 4-way warning flashers.   [Reply]  [No Email]
