watcha mean by "euro"? here are a lot of styles that can be considered euro but then again, if you look at current euro mags you'll see styles borrowed from the states and japan. still, the only mod i can think of is a vinyl overlay (e.g. from batmobile), painting it or shaving it off all together.
Exactly what I was thinking. I don't know if bat makes an overlay for the brake light other than the top of it. Shaving it is probably illegal. Painting it or custom overlay might be your only option and might be illegal also.
