Lamps for 2005 C6 Coupe

[caddy]

I've been seeing alot of advertising for these new lamps that are made up of a bunch of LED's that just stab or twist right into existing sockets on cars/trucks, I was wondering if anyone out there has used any of these lamps? and if so have you tried them in the newer model Vettes? And do they work, there kinda expensive......
They look cool and are supposedly brighter but I know of no one that has purchased/used them any help would be greatly appreciated, oh and where did you purchase them.
thanks
