I get all of my LED's from JP_Warden2002 on ebay (my fav seller).
ANYWAYS.....reading this how to got me excited. I went into my LED supply and pulled out a 1W flank LED bulb 168/194 bulb.
Took my screwdriver and flashlight.........changed the trunk bulb out in about 1 minute flat. Soooooooo much whiter, about the same brightness though. Very happy :)
