Ever part that ive bought off eBay has worked fine. Ive never bought any taillights though. and like tnhillbilly said, look at the sellers feedback, i avoid anyone under 98%. And another thing to keep in mind is the shipping costs. A lot of sellers list there products low so that you think there cheap, but then add more to the shipping price. And one last thing that i highly recommend, if you do decide to buy off ebay, make sure you use paypal! that way you know your covered, if you don't receive your item you'll most likely get your money back.
