I pulled what appeared to be a cover off of the square box that i was plugged into last night, wow like you say Steve, crazy stuff. It reminds me of some of the german stuff i used to run into on the many S class cars i used to have over the years.
anyway, i plugged the bulb back into that square hole in the back and turned the lights on, yep that clear plastic tubing was lit up as well but i couldn't see any light in the tray or for that matter anywhere but at that clear plastic tubing and at the bulb,lol
opening and closing the ashtray didn't seem to give that clear tubing a purpose in life, haha. I imagine the truth will come to me about this situation someday, but for now I'll plug the bulb into that square hole, upper right rear and maybe someone else can tell me about this one, lol
