I installed the 9005 subst HIR bulb into my lowbeam today (misread the auction and bought one single bulb instead of a pair).
I'm inclined to believe the claimed light output, it is much much brighter than the other side which is a 9005 modded to fit.
But I'm really afraid the reflector isn't adequate for this bulb (the highbeam one fitted). It's throwing some weird reflections out through the side. I haven't been flashed yet, and I haven't left the city yet either so can't really comment on it further. But we'll see how well they work.
