The Philips Osram and VOSLA HIR1(9011)Halogen
Infrared Reflective bulbs are among the most efficient
halogen headlight bulbs in existence. The first commercial
application was the high beam of the first-generation
Dodge Viper, then in the low beam of the 2003 Nissan
Maxima's high/low beam lamps, and since then they have
been specified as original equipment in a wide range of
vehicles, off-road equipment, and snow plows.
Toshiba, which was formerly the primary supplier, no
longer makes these bulbs. They are currently manufactured
to OE quality and performance specifications by Philips,
Vosla, GE, and Osram. We supply Vosla, Philips, and Osram
HIR bulbs. As with all bulbs, the design varies slightly
depending on the manufacturer. It's most productive to
focus on the bulb's performance, not on its design
details. For example, there's a rumor on the internet that
the Toshiba bulbs were "real HIR bulbs" and the Philips
bulbs aren't. But our objective testing shows the Philips
product running 10.8% brighter than the Toshiba.

NOTE: The picture above is the original GE prototype. Other than the mounting tabs on the Base, both the 9011 and 9012 now have a conventional "headlamp" shape.
