The first automotive "headlights" consisted of a pair of kerosene oil lamps mounted on the front of those primitive vehicles. The next innovation came around 1900 with the introduction of acetylene gas lamps. Electrical automotive lighting wasn't common until about 1910, after which it was virtually unchanged for the next forty years until the introduction of sealed-beam headlights in the 1950's. Today, PIAA is at the cutting edge of automotive lighting technology with innovative products such as the PIAA Super Plasma GT-X Bulb. This bulb uses the company's patented Xtreme White technology that makes much more efficient use of available energy resources. This results in a bulb that provides the same illumination as a 110 watt bulb while consuming half that much energy. The PIAA Super Plasma GT-X Bulb is almost like having twin suns mounted to the front of your vehicle, as this bulb's output is rated at 5000 Kelvins (natural full sunlight is 5250 Kelvins). The bluish tint of the PIAA Super Plasma GT-X Bulb's light not only provides superior illumination, it actually makes a fashion statement as well, giving your car an aggressive new look.
