The Nissan 1200 high beam and low beam headlight bulbs both utilize the H6024 size. The replacement chart covers vehicle production spanning 1971 to 1973.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan 1200 uses the H6024 bulb size for both high beam and low beam headlights across the 1971-1973 model years.
The H6024 is an ANSI-standard sealed beam unit recognized in the United States and Canada, operating at 12 volts.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly, meaning the entire unit is replaced rather than an individual bulb.
The H6024 follows the 7-inch round sealed beam format, a standardized size that was federally regulated for use in North American vehicles during this era.
Because the high beam and low beam positions share the same H6024 specification on the Nissan 1200, a single unit type serves both functions, which is characteristic of a dual-filament sealed beam design.
The ANSI standardization of the H6024 means the unit conforms to defined performance and physical specifications set by the American National Standards Institute, ensuring interchangeability across vehicles that share this fitment.
