Summary:
Can I replace my 9006 low beam bulbs with 9011 hi-beam HIR bulbs safely?

Details:

I just got my second accord (from a 1989 to a 1997) and I'm not impressed with the low beams at night, simply too dim for even normal conditions.

I have in the past used 9005 bulbs (no cap, 1700 lumen) as a brighter replacement for 9006 (capped, 1000 lumen) bulbs by cutting away some of the top tab and the inner guide tabs as outlined here (search that thread for "More Light").

I have also read about HIR bulbs being used as replacements (use "select all" on that site to see the black text on black background):
9005 --> 9011 (hi-beam)
9006 ---> 9012 (low-beam)

I see that it would be possible to cut the 9011 bulb fitting to match a 9006's fittings, thus it is possible to put the 9011 in the 9006 lo-beam position.

My question:
Is this a bad idea for some reason I am unaware of?

Is the brighter bulb going to melt the headlight? The wiring harness?
Is the bulb going to have a very short life? (used on new Maximas so I assume it has acceptable bulb life in that application)
Something else (fire, melting, police attention, etc)? (Seems that if your lights are properly aimed the 9005 in 9006 mod does not attract attention, so this ought to be the same but I'm guessing)

Also, if anyone knows where to get the 9011 bulbs for less than $29 on ebay, please let me know.

Thanks ahead of time for your feedback
