Mercedes-Benz G63 AMG headlight bulbs use D1S and H7 sizes for high beam and D1S for low beam applications. The replacement chart covers 2013 to 2018 model years with bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The D1S bulb type appears across both high beam and low beam headlight positions in the Mercedes-Benz G63 AMG specifications, making it the most prevalent bulb type listed for this vehicle.
The D1S is a high-intensity discharge (HID) bulb that operates using a xenon gas arc rather than a traditional filament, producing a bright, white light output with relatively low power consumption compared to halogen alternatives.
D1S bulbs have an integrated igniter built directly into the bulb housing, which distinguishes them from D2S bulbs that require a separate external igniter. This integration affects direct replaceability between the two types.
For the 2013-2016 model years, the high beam position lists two separate bulb sizes: D1S and H7, with the H7 entry noted specifically for vehicles equipped with HID headlamps. This indicates a trim or configuration split within those model years.
The H7 is a halogen bulb with a two-pin PX26d base, operating on a single filament. Its presence in the high beam position on HID-equipped vehicles suggests it may serve a supplementary or projector-specific role rather than functioning as the primary HID source.
The 2017-2018 model years list only D1S for the high beam position, without the H7 alternative entry that is present in the 2013-2016 data.
D1S and H7 bulbs are not interchangeable. They differ in base type, operating voltage, and ignition requirements, meaning the correct bulb for a given G63 AMG depends on the specific headlamp system installed in that vehicle.
The low beam headlight position lists only D1S across all model years from 2013-2018, with no alternative bulb size noted for any configuration.
