The Mercedes-Benz C36 AMG brake light requires a P21W bulb size for the specific lighting components. Data for the specified vehicle covers the period from 1995 through 1997.
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 P21W bulb for brake lighting across the 1995-1997 model years.
The P21W is an ECE-standard single-filament signalling bulb rated at 12V and 21W, fitted with a BA15s bayonet base.
The BA15s base is a single-contact bayonet fitting, which physically prevents substitution with dual-contact variants such as the BA15d without modification.
The center high mount stop light on the C36 AMG uses the H21W bulb for the 1996-1997 model years.
The H21W is also an ECE-standard single-filament signalling bulb rated at 12V and 21W, but it uses a BAY9s base rather than the BA15s found on the P21W.
Although the P21W and H21W share identical voltage and wattage ratings, their base types are mechanically incompatible with each other, making the two bulbs non-interchangeable.
Both the P21W and H21W conform to ECE regulations, reflecting the European market orientation of the C36 AMG.
