The Nissan B210 high beam and low beam headlight bulbs both utilize the H6024 size. The replacement chart covers vehicle production spanning 1973 to 1978.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan B210 uses the H6024 bulb size across all listed model years, spanning 1973-1978, for both high beam and low beam headlight positions.
The H6024 is an ANSI-standardized sealed beam unit, meaning the lens, reflector, and filament are fused into a single non-serviceable assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
The H6024 unit is a 7-inch round sealed beam, a format that was regulated under US and Canadian lighting standards and shared across many vehicle makes of that era, which contributes to broad parts availability.
The H6024 operates at 12 volts, consistent with the standard 12V electrical systems found in passenger vehicles of that period.
Because the same H6024 unit serves both the high beam and low beam positions on the B210, the vehicle uses a dual-headlight arrangement where each sealed beam housing handles a single function rather than a single unit switching between two filaments.
The ANSI standardization of the H6024 means the unit conforms to fixed specifications for size, light output, and connector interface, making it interchangeable with H6024 units from different manufacturers without fitment modification.
