The Mercedes-Benz G500 high beam and low beam headlight bulbs utilize a 9003 or D1S bulb size. The replacement chart contains specifications covering 2002 through 2008 vehicle production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the most widely represented type across these specifications, appearing in both the high beam and low beam positions for the Mercedes-Benz G500 across the 2002-2007 model years, as well as in the 2008 model year when equipped with halogen capsule headlamps.
The 9003 is a dual-filament halogen bulb operating at 12V with a 60W filament for high beam and a 55W filament for low beam, fitted with a P43t base. Its dual-filament design allows a single bulb to serve both beam functions within one housing position.
Because the 9003 handles both high and low beam output through separate filaments, the same bulb size is listed under both the high beam and low beam sub-parts for every applicable year in these specifications.
The 2008 Mercedes-Benz G500 introduced a second headlamp configuration alongside the halogen option, with HID-equipped vehicles requiring the D1S bulb for both high beam and low beam positions.
The D1S is a high-intensity discharge xenon bulb rated at 85V and 35W, using a PK32d-2 base with an integral ignitor. It is designed exclusively for projector-type housings and operates under the ECE standard used in European and worldwide markets.
The D1S and 9003 are not interchangeable. The D1S requires a projector-type housing and a ballast system to generate the high voltage needed for arc discharge, while the 9003 operates on a standard 12V halogen circuit.
For the 2008 model year, the correct bulb type depends entirely on which headlamp system is installed. Halogen capsule headlamp vehicles take the 9003, while HID headlamp vehicles take the D1S, and substituting one for the other is not supported by these specifications.
