Just ordered a pair of 9012 HIR bulbs.

My reasoning:
(1) longest life (longer than over amped 9005's or 9011's, similar run time to traditional 9006 bulbs)
(2) Correct wattage (related to above, but also easier on the alternator in the long term)
(3) Less risk of bothering other drivers with too much light leaking into their view, something no one likes.

Reasons against:
(1) Expensive - a pair of Philips Vision Plus bulbs from Aid-auto.com would have been $22 shipped, two 9012's were $55 shipped from Candlepower
Further, the 9011 bulbs would have been the same price and significantly brighter, but at a substantial loss of run time (apparently about 33% of the run time relative to the 9012 according to the technical spec sheets and Dan Stern Lighting, a great resource).
(2) Only slightly brighter than the VisionPlus 9005:
VisionPlus 9005 - 1700 lumens
Toshiba 9012 - 1875 lumens

So is the longer run time and slightly higher lumen rating worth an extra $33? It's a tough call, but I think the safety, longevity, limited risk of damage to my wiring harness from over amp'age, and (less so) extra brightness are enough to justify the extra $33. I hope they last a long time though!

Should be here in a few days, pictures in less than a week of all goes well.
