Upgrade your factory headlights the right way, and install a bi-Xenon projector system from Deep Space Lighting on your first-generation Mazda6. Improve low beam light output significantly, and with the projector’s shutter you add a faster-acting, brighter high beam.
Both versions include Morimoto G4TL-R Projectors, 3-piece aluminum Mazda6 mounting brackets and hardware, and high beam shutter wiring harnesses. Since the 06-08 Grand Touring and Mazdaspeed6 headlights came with Xenon headlights, bulbs, ballasts, and igniters are not needed; installing new bulbs is recommended though, and they can be found here.
The version for factory halogen headlights adds low beam adapter harnesses, D2S bulbs, Morimoto XB ballasts, and igniters.
Headlight housings can be removed from the car in 15-30 minutes. Installation in the housings takes 30 minutes to 1 hour, and requires access to a heat gun or oven.
