The Mercedes-Benz C36 AMG front fog light requires an H3 bulb size while the rear fog light uses a P21/4W bulb size. The replacement chart covers 1995 to 1997 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz C36 AMG uses the H3 bulb for the front fog light position across the 1995-1997 model years.
The H3 is a single-filament halogen bulb rated at 12V and 55W, built to the ECE standard used in Europe and worldwide, with approval also extended to the United States and Japan.
The H3 bulb uses a PK22s base, a pin-type connector that is specific to this bulb family and is not interchangeable with standard bayonet or wedge-base halogen types.
The rear fog light position on the C36 AMG takes the P21/4W bulb across the 1995-1997 model years.
The P21/4W is a dual-filament signalling bulb rated at 12V with two wattage outputs: 21W on the primary filament and 4W on the secondary filament.
The P21/4W uses a BAZ15d bayonet base, which features offset pins to ensure correct polarity orientation during installation. This offset design prevents substitution with single-filament bayonet bulbs that share a similar base profile but carry a different pin configuration.
