Digging my old post up. I have 9005's and HIR1's sitting around (9011).
Installed some in fogs and in lows to have a comparison vs the stock 9145 fogs and my upgraded HIR2's (9012's) in my lows.
Looks like the 9011's in the fogs may be a bit blinding, although i wasn't on level ground. I'll have to try it again and drive it around to see what the cutoff is like @ a distance.
STock (older) 9145 fogs
9011's in drivers side fog and 9145's in passenger (you can see that I borrowed my HIR1's from my denali in the background)
Ok and 9011's in passenger side low beam vs 9012's in drivers side. Note the increased color temperature (often measured in kelvins) Looks the the HIR1's are more of a cool white (more pure white, than the HIR2's which appear to be warmer (more yellow)
Cutoff still seems fine against the garage door (the light bleed you are seeing above the cutoff is actually a reflection from the metal door), hard to tell the difference in brightness there though.
Keep in mind that I am comparing HIR1's to HIR2's If i was comparing HIR1's to 9006 (our stock bulbs) the difference would be HUGE
This is with no relays or any modifications to the vehicle @ all. I have simply modified the base of the bulb so that it fits in our housings and the little guide tabs in the base of the bulb so that our wiring harness plugs in.
The 9011's are available @ rockauto for ~$25 shipped for a pair. Best bang for your buck lighting upgrade possible IMHO.
In retrospect this deserves its own thread since I suppose the title doesn't really apply anymore.
