well i went out and got the h7 silverstars..but they dont fit. and i can tell they are different some stock cause the stock gap between the prongs are much bigger than the silverstars..so if i got the wrong ones which ones to i get. the only other ones i saw at autozone was the ones " for motorcycles". but they have a third prong and are bigger in bulb size than stock. so i didnt wanna return these till i knew exactly when ones to get.

thx, steve

 

i'm not exactly sure what the RR takes, but if it's like the F4i, it is the H7s.
the bulbs that you removed sits on a little harness. so you'll need to remove that from the old bulb, insert the new bulb into it and then plug the wiring harness back in.

RR is the same way , what Tahoe SC said

 

dont know about the RR's. the H4(9003) fit perfectly into mine. It's a philips bulb.

 

Yep - the PIAA bulbs i got for my RR, i had to pull the black housing off the original bulbs & fit it to the PIAA bulbs.
