PIAA GT-X replacement bulbs are designed with an exclusive purple low beam and an Xtreme White high beam. A purple topcoat gives the headlamp a bluish-purple look even when the lamp is turned off. GT-X bulbs feature PIAA's Xtra high efficiency technology that produces greater light output than the bulb's rated power consumption (for example, a bulb that consumes 45/65W of electricity has a light output that is similar to most 95/120W bulbs). GT-X bulbs are street-legal in Canada and all 50 U.S. states. Low beam. For models without HID headlamps.
