The Mercedes-Benz 380SEC uses H6054 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1982 to 1983 model 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 H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. It conforms to ANSI standards applicable in the United States and Canada, meaning the optical lens, reflector, and filament are all housed within a single sealed glass assembly.
Because the H6054 is a sealed beam unit rather than a bulb-and-housing system, the entire assembly requires replacement when the filament fails. There is no separate replaceable bulb within the unit.
The Mercedes-Benz 380SEC uses the H6054 sealed beam unit for both high beam and low beam headlight positions across the 1982-1983 model years. A single bulb type therefore serves both lighting functions on this vehicle.
The H6054 designation follows ANSI standardization, which means units from different manufacturers sharing this designation are dimensionally and electrically interchangeable, provided they meet the same 12V specification.
