Ford Granada high beam and low beam headlight bulbs utilize 3 distinct sizes: H4651, H4652, H6054, and H6024, with the bulb specifications varying across production years. The replacement chart documents headlight bulb sizes for Granada models spanning 1975 to 1982.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Granada headlight specifications span the 1975-1982 model years, covering three distinct sealed beam unit types across both high beam and low beam positions: H6024, H6054, H4651, and H4652.
All four bulb types listed are ANSI-standard sealed beam units rated at 12V. In a sealed beam design, the reflector, lens, and filament are fused into a single glass unit, meaning the entire assembly is replaced rather than an internal bulb.
The H6024 is a 7-inch round sealed beam unit used in both the high beam and low beam positions for the 1975-1977 Ford Granada. Because both positions share the same part number, a single unit type serves the full headlight assembly for those years.
The H6054 is a 5x7-inch rectangular sealed beam unit fitted to both the high beam and low beam positions for the 1978-1980 Granada. As with the H6024, the shared part number across both positions indicates a single unit type per side.
For the 1981-1982 Granada, the high beam and low beam positions use different part numbers: H4651 for high beam and H4652 for low beam. Both are 4x6-inch rectangular sealed beam units, with the H4652 described as a variant of the H4651.
The distinction between H4651 and H4652 in the 1981-1982 years reflects a position-specific filament configuration. Despite sharing the same physical 4x6-inch rectangular housing, the two units are not interchangeable between high beam and low beam sockets.
The H6054 and H6024 units, while both rectangular and round sealed beams respectively, differ in physical size and are not interchangeable with each other or with the 4x6-inch H4651 and H4652 units used in later years.
All bulb types across the full 1975-1982 range conform to ANSI standards applicable in both the United States and Canada, indicating consistent regulatory compliance across the production run of the Granada in North American markets.
