I also got the ebay version with the colored R8 logo. I like how it matches the custom mats that a lot of us got [see this thread: https://www.r8talk.com/forums/22-sal...oor-mats.html]
They aren't super bright in the day, but at night, they are really cool.
PL73, Typ 4M Q7 
Typ 42 R8 Spyder

Audi - PL71, Typ 4M Q7 Diesel 
BMW - E70 X5d ; E90 335i ; E53 X5 ; E46 M3 Convertible SMG 
MB - W204 C300 ; W211 E350 ; W203 C55 AMG 
Porsche - 997.1 Cabriolet ; 996 C2 ; 986 Spec Boxster 
I've had mine for about 8 months still working so I guess they're good. All these projector lamps fade over the lifetime apparently. I would say mine are still as bright. For as cheap as they are I'm ok if they go out. I'm sure the dealer has these at a ridiculous price compared to the $15ish price tag.
Thanks for the link, I just ordered a set, Very Cool
