Since 1963, PIAA has been recognized as a leader in the development of automotive lighting technology. In recent years, they have been in the development process of a few other product lines such as air dams and windshield wipers, but the company's main focus has been and continues to be automotive lighting solutions. When it comes to driving in fog and other poor weather conditions, the PIAA Ion Crystal Bulb is an ideal choice, having been developed for exactly that purpose. The PIAA Ion Crystal Bulb is especially designed to emit a longer, single-wavelength beam that is not scattered by water molecules like multi-wavelength white light. Less of the PIAA Ion Crystal Bulb's yellowish light if reflected by these molecules and back into your eyes, meaning better illumination in fog, blizzards and other heavy conditions. PIAA's patented Xtreme White technology enables this bulb to produce 85 watts of light while it draws no more than 55 watts of power from the system. The PIAA Ion Crystal Bulbs mount right into your car's stock OEM receptacles without modifications, and will not place any unusual stress on your present electrical system. Heat resistant glass and welded metal focus rings ensures proper fit and long life. Gearhead hobbyists desire great technical assistance when they buy good quality automotive parts.
