The Nissan 310 high beam and low beam headlight bulbs utilize H6054 and H6024 bulb sizes for illumination. The replacement chart covers vehicle production years spanning 1979 to 1982 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan 310 uses two sealed beam headlight types across its model years: the H6054 and the H6024. Both are ANSI-standardized units approved for use in the United States and Canada, and both operate on a 12-volt electrical system.
The H6054 is a 5x7-inch rectangular sealed beam unit. It appears on the Nissan 310 for the 1981-1982 model years in both the high beam and low beam positions.
The H6024 is a 7-inch round sealed beam unit. It was fitted to the 1979-1980 model years, again serving both the high beam and low beam positions.
Sealed beam headlights are self-contained assemblies in which the lens, reflector, and filament are fused into a single unit. When a filament fails, the entire assembly requires replacement rather than an individual bulb.
The high beam and low beam positions share the same bulb type for each respective model year. On the 1981-1982 310, both positions use the H6054, while on the 1979-1980 310, both positions use the H6024.
The H6054 and H6024 are not interchangeable. The rectangular 5x7-inch format of the H6054 and the round 7-inch format of the H6024 correspond to physically distinct housing shapes, making cross-year substitution incompatible without modification to the vehicle.
