The E90/91 LCI w/ xenon and E92/93 Pre-LCI use a reflector to pipe light to the outer ring, and stray light is put foward to the inner ring--
(note how little light gets reflected to the outer ring, and how much just simple passes foward--explains why the light goes out)
I'm VERY curious about how E92-Lighting's "revolutionary" product will bypass this inherent engineering flaw while still remaining plug-and-play.
Put me in the "skeptical until pics of product" camp
Is that diag pic of the e90 lci angel eyes?
