The Philips, Osram, Sylvania, and VOSLA HIR2(9012) 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.
