I intend to replace the stock high-beam bulbs in my 2005 Q45 with the ones described below.I am concerned about bulb incompatibility after seeing so many posts where aftermarket bulbs cause problems.

Does anyone see a problem with these? (I hope not; they seem to be the answer to my prayers)

Replace the existing 9005 bulbs with 9011. The new bulbs are not sometinted or overwattage version of 9005, but rather employ a relatively newtechnology called HIR, Halogen Infrared. The mechanical dimensions of thebulb are all virtually identical to the 9005, but the bulb glass isspherical instead of tubular, with the sphere centered around thefilament. There is a "Durable IR Reflective" coating on the sphericalglass. Infrared = heat, so the coating causes heat to be reflected back tothe filament at the center of the sphere. This causes the filament tobecome much hotter (producing more light) than it can by passingelectricity through it, *without* the shorter life or greater heatproduction that comes with overwattage bulbs (to say nothing ofoverwattage bulbs' incompatibility with stock wiring.)

Here's the comparison:

stock: 9005, 12.8V, 65W, 1700 lumens, 320 hourscompare: 9005+50, 12.8V, 55W, 1830 lumens, 175 hoursnew: HIR1, 12.8V, 65W, 2530 lumens, 320 hours

These bulbs are spendy - $27/ea - but their cost is worth considering incontext: Any number of companies will charge you more than this for atarted-up 9005 with blue colored glass (PIAA and Sylvania Silverstar cometo mind) that doesn't produce more light and has a very short lifespan.

The HIR bulbs have a double-wide top ear on the plastic bulb base, this isto comply with the law requiring different bulbs to have different bases.The extra-wide plastic top ear is easily trimmed or filed to make the bulbfit your headlamp's bulb receptacle. Once that's done, they go directlyinto the headlamp, and the existing sockets snap on.

these bulbs sound like the Toshiba HIR bulbs,very highly rated and reccomended-they are used OEM by some manufacturers-I think the viper uses them,among others.
