"The Professionals Choice
PIAA Lamps are the professionals choice for high performance driving, spot, fog and automotive lighting. Dependable and reliable under the most severe racing conditions, they are used by World Rally and National Rally Champions.

Advanced Tough Design
Tough PIAA lenses are computer designed for optimum performance and are made of hardened prism glass to withstand the rigours of off-road and normal highway hazards. PIAA's lamps feature a specially designed polyphenylene sulphide composite, alumimium or stamped steel housing. These materials make it possible for PIAA lamps to operate under higher wattage bulbs without sacrificing bulb life. PIAA Quality makes PIAA lighting the serious drivers choice.

HID Lamps
High Intensity Discharge H.I.D. Lamps create a light source that is produced by a stabilized arc that burns at a much higher color temperature which creates a whiter light output than a standard halogen bulb."
