The BMW 2800 uses an H5001 bulb size for high beam headlight operation and an H5006 bulb size for low beam headlight operation. The replacement chart covers 1969 to 1971 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 BMW 2800 uses sealed beam headlight units across all listed model years (1969-1971), meaning the lens, reflector, and filament are fused into a single assembly. When the filament fails, the entire unit requires replacement rather than a bulb swap.
High beam positions on the BMW 2800 use the H5001, a 4-inch square sealed beam unit operating at 12 volts. It conforms to ANSI standards applicable in the United States and Canada.
Low beam positions use the H5006, a 5.75-inch round sealed beam unit also rated at 12 volts and built to the same ANSI standard as the H5001.
The H5001 and H5006 are physically distinct units. The square profile of the H5001 and the round profile of the H5006 make the two non-interchangeable with each other, as each occupies a specifically shaped housing in the vehicle.
Both the H5001 and H5006 designations follow ANSI standardization, which defined sealed beam sizes and electrical ratings to allow consistent fitment across vehicles sold in North American markets during that period.
The 12-volt rating on both units is consistent with the 12-volt electrical systems standard in passenger vehicles of that era, distinguishing them from the 6-volt sealed beams used in earlier automotive applications.
