i bought mine on ebay. at first i wasn't a huge fan on the U-shaped lights, but it's something i got used too. no problems with them and they are super bright. on a dark road they will light up objects way behind you when you hit the brakes. only thing i'm afraid of is damaging them on a trail since they are so expensive, but i had to go the aftermarket way, since my factory taillights were giving me all sorts of trouble.
