just buy the ebay specials, you're better off with those. why not spend $50 more just to get it new, instead of replacing them sooner rather than later.
Pepboys has a great selection... plus have a set of hella 500s knock offs made by optix {Hella's sub brand} only $40 and they produce better light than 500s I have a set on my LGT ill never buy a set of 500s again.
