The LEDs I used are the flexible LED strips from Oznium:
I wasnt sure if the 9.5 inch ones were long enough so I bought the 20" inch ones and cut them. Make sure when you cut them, that you cut 3 LEDs at a time(cut 3,6,9,etc LEDS at a time, not like 4, 7, or whatever).
dont buy the amber strip though (behind the stock amber reflector, it will appear orange, I think knightryder from v6p.net did this but not sure) he did get yellow led strip and behind the stock reflector, matched the parking bulb 100%
of course you could just remove the reflector and put in an amber led strip (but not sure how amber it will turn out to be)
I also would like to do something like this (white leds though) eventually
