New D1S / D1R xenon HID headlight ballast, a replacement for Bosch Gen 6 A1669002800 Q03 (Bosch 1 307 329 312 01), for factory HID headlights on many 2009-2019 Mercedes-Benz, BMW, Mini, Volvo, Kia, Land Rover and Maserati models. Replacement for Bosch, not a Genuine Bosch or OEM part. Free shipping to the lower 48.

Fix a Dark or Flickering HID Xenon Headlight

The ballast powers and ignites the factory D1S / D1R xenon bulb. When it fails the headlight can flicker, cut out or stay dark even with a good bulb. Swapping just the ballast costs far less than a complete headlamp.

Fits

Fits vehicles with the factory HID Xenon headlamp. Match the part number on your old module before ordering.

Installation

1. Turn the headlights and ignition off and disconnect the negative battery cable. Let the bulb and ballast cool.
2. On the Mercedes-Benz, BMW, Mini and other listed models the ballast is mounted to the bottom or back of the headlamp housing. Depending on the vehicle you may reach it through the wheel-well liner, or you may need to loosen the bumper cover and unbolt the headlamp to pull it forward.
3. Unplug the main power connector and the igniter/bulb lead, then remove the screws holding the ballast to the housing.
4. Compare the part number on your old ballast to the numbers above before fitting the new one.
5. Fit the new ballast, refit its screws and lock every connector fully. The seller lists it as direct plug-and-play.
6. Reinstall the headlamp and trim, reconnect the battery and test low beam (and high beam if bi-xenon).
