Good suggestion. If it turns up again I will. I almost did the last time. What I would really like to know, though, is whether there is something behind the cover amongst the other lights that could make a round, bright red light, in the middle of the group.Take a pic
I don't think so. It was emitted from inside the rear light group housing. That is not open to the inside of the cab.Possible reflection from inside source on the window?
Hmmmmm. I'm going to have to look at mine.The red light emitted a small red, bright light in the middle of the light group above the rear window.
