The Triumph TR6 high beam and low beam headlight bulbs both utilize the H6024 size. The replacement chart covers vehicle production spanning 1969 to 1976.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Triumph TR6 uses the H6024 bulb size for both high beam and low beam headlights across all model years covered in the specifications, spanning 1969-1976.
The H6024 is an ANSI-standard sealed beam unit recognized in the United States and Canada, operating at 12 volts.
The H6024 is a 7-inch round sealed beam, meaning the lens, reflector, and filament are fused into a single glass unit rather than housing a separate replaceable bulb.
Because the H6024 is a sealed beam unit, the entire assembly is replaced when the filament fails, not an internal bulb component.
The Triumph TR6 uses the same H6024 specification for both the high beam and low beam positions, indicating a dual-function sealed beam arrangement rather than separate single-function units for each beam mode.
