The Mercedes-Benz 280SL uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1968 to 1971 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 H6024 is the sole bulb type specified across all listed model years and lighting positions for the Mercedes-Benz 280SL, covering both high beam and low beam headlights from 1968-1971.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts, conforming to ANSI standards applicable in the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly, meaning the entire unit requires replacement rather than an internal bulb alone.
The H6024 format was a standardized sealed beam type, which means units from different manufacturers sharing the same designation are generally interchangeable at the physical and electrical level.
Because the 280SL uses the same H6024 specification for both high beam and low beam positions across all four listed years, the vehicle relies on the sealed beam unit to serve dual lighting functions rather than separate bulbs for each beam mode.
The ANSI standardization of the H6024 means its physical size, voltage rating, and connector interface conform to a regulated specification rather than a proprietary one, which affects parts sourcing and cross-compatibility with other vehicles using the same standard.
