Key Features

Better Lit Paths, Confident Travels: With 6500K cool white luminous output, D1S units mimic the native arc brightness of OEM xenon bulbs. Well-defined light demarcation forms a precise beam cutoff, avoiding dazzling drivers from oncoming lanes.

OEM Installation Compatible: Outfitted with an intelligent decoding drive, the bulb connects directly to the factory HID ballast. Existing vehicle wires remain intact, and all built-in AFL, AFS steering functions stay fully intact.

Advanced Cooling: Featuring red copper substrate, internal high-speed blower, fin-type heat dissipating setup, and aerospace-standard aluminum shell, the bulb achieves superior thermal control and keeps consistent output over 50000 hours of runtime.
