Direct HID Bulb Replacement

Compact, one-piece body fits under the factory dust cap. Remove the HID bulb, insert the D-Lumina LED and connect to the OEM ballast – no extra drivers or adapters required.

Ballast-Compatible, Error-Reduced

Clean, Focused Output

Optimised emitter positioning maintains a sharp projector cut-off with strong reach and wide foreground. Re-aim after installation for best results.
