Porsche 924 headlight bulbs utilize the H6024 size for both high beam and low beam applications. The replacement chart covers vehicle production spanning 1977 to 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Porsche 924 uses the H6024 bulb size across all listed model years, 1977-1988, 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 widely adopted in North American automotive lighting standards and remains physically interchangeable across many vehicles that share the same ANSI specification.
The H6024 operates at 12 volts, consistent with the standard electrical systems found in passenger vehicles of its era.
Because the H6024 serves both the high beam and low beam positions on the Porsche 924, the vehicle uses separate sealed beam units for each function rather than a single dual-filament assembly per side.
The ANSI standardization of the H6024 means that fitment is governed by a fixed physical format, and any H6024-rated sealed beam unit from any manufacturer is dimensionally compatible with the specified positions on the Porsche 924.
