Yeah, the orange dome kept flipping upside down. I ended up turning the headlite upside down, laying on my back looking up through the front of the light, and reaching my arm around to come in the hole from behind the light. With this method, the dome would sit the correct way for the edges to be accessible from the hole. PITA!
My car is black, so I spray tinted the corners and taillights black as well. I think it looks pretty good. I havn't taken pics of it yet cause the car is so dirty. But when it stops raining and I get a chance, I post pics.What color did you tint the corners?
