Also for LED's to run bright they need a heat sink or else it will melt itself in an enclosed environment. The current needed to light these LED's are insane.
Yes, they were in full testing in 2008 for approximately 1 year before being released and have been in my M3 since 2009 with no issues, even on later 2011 models with FRM3 and early 2007 non-M models which were problematic in the past in the development phase.
AIBs also have a 3 year warranty included with each kits - longer than the competition, and possibly more than most have owned their M3s.
The AIB project is very interesting, as their head engineer main project is replacing airport runway lighting with LED fixtures, and a proud e92 owner - a large part of which made this project come alive.
