First of all, is this a free mod? What color would it blink when it's done? Is it street legal? Is there an alternate way in which you can do this without cutting anything? I read several posts and they say that it's very hard and there are many things that could go wrong.. I saw many pics of the finished product and I like them very much.. So, I think that it's worth all of the trouble that I have to go through, but I just want more info on them and maybe another easy way to do it. Thanks
