The Mercedes-Benz C36 AMG uses a 2357NA bulb of P21/5W size for the front turn signal and a P21W bulb for the rear turn signal. The replacement chart covers 1995 to 1997 model 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 three distinct bulb types across its turn signal positions: the 2357NA, the P21/5W, and the P21W, each serving specific model years and locations.
The P21/5W and P21W are both ECE-standard bulbs, meaning they conform to European and international regulations, while the 2357NA follows the ANSI standard used in the United States and Canada.
The 2357NA and P21/5W are dual-filament bulbs, meaning each contains two separate filaments within a single housing, allowing them to serve more than one lighting function simultaneously.
Both the 2357NA and P21/5W share a BAY15d bayonet base, which is an offset dual-contact base. Despite this shared base type, the two bulbs are not interchangeable due to differing wattage ratings and regulatory standards.
The 2357NA operates at 26.9W on its primary filament and 8W on its secondary filament, while the P21/5W operates at 21W and 5W respectively, reflecting a notable difference in power output between the two dual-filament types.
The P21W is a single-filament bulb rated at 21W and uses a BA15s bayonet base, which is a single-contact base. This base type is physically incompatible with the BAY15d base used by the dual-filament bulbs in the front turn signal position.
The 2357NA features natural amber glass, which produces an amber-colored output without the need for an amber-tinted lens, a characteristic not shared by the P21/5W or P21W.
The front turn signal of the Mercedes-Benz C36 AMG shifted from the P21/5W in 1995-1996 to the 2357NA in 1997, representing a change in both the regulatory standard and the bulb specification for that position.
The rear turn signal position uses the P21W across all three model years covered in the specifications, from 1995-1997, making it the only position with a consistent bulb type throughout the listed production period.
