anyone know how to replace?
Well if it is a stock one there are two little srews on either side to undo. Some are differet but I think T15 is the right size. Either before or after you look on the inside of the truck to unplug it from the harness and then pull from the outside, and it all should come out. You then get to order a new one.
^only need a new one unless it is broke or a LED is out. Didn't know why eles you would take it out, but I guess painting and stuff duh...
