Actually if you think about it, it makes a lot of sense! Take GM for

you loose dash lights, you know you have lost tail lights as well. Kind of a
red flag. So as a "COURTESY" Das uncle Wilhelm, is saying if you can't see
to move around in your van, your gonna get hot under the collar.
Lame I know, but I've got it out of my system for the week end!  ;~o
