I have an integrated tail on my bike. I love it because it cleans up the ass end of the bike. I never had any problem with the light, ie. other riders/drivers not seeing it or misunderstanding my intent. now i heard a rumor that they are illegal, but never had any run ins with the po po and never had a problem getting an inspectioin sticker on it. To each his own, sopme love it, some hate it, i say go for it brother
