i used window spray tint, i guess they use it in racing applications for windows, assuming windsheilds to block the sun, and it can be found at any hobby shop as well. The cops will bug you about it around here, i havent driven my truck with them yet, but it cant be legal unless you get brighter than stock bulbs. A friend has been pulled over for them.... just to let you know, but at least it just comes off with alcohol, so you can always take it off. No pictures of them lit because my truck doesnt have a battery as of yet, it is all stripped and being bagged, sorry.
