The Audi Fox high beam headlight bulb size includes H5001 and H6024 options, while low beam headlight bulb size encompasses H5006 and H6024 specifications. The replacement chart covers 1973 to 1979 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Audi Fox uses three sealed beam unit types across its headlight positions: H5001, H6024, and H5006. All three conform to ANSI standards recognized in the United States and Canada and operate on 12V electrical systems.
Sealed beam units integrate the filament, reflector, and lens into a single fused assembly. When a sealed beam fails, the entire unit requires replacement rather than an internal bulb swap.
The H6024 is a 7-inch round sealed beam unit. It serves as both the high beam and low beam headlight on the Audi Fox for model years 1973-1976, meaning a single unit type covers both functions in those years.
The H5001 is a 4-inch square sealed beam unit used exclusively for the high beam position on the 1977-1979 Audi Fox. Its square form factor makes it physically incompatible with round headlight housings.
The H5006 is a 5.75-inch round sealed beam unit assigned to the low beam position on the 1977-1979 Audi Fox. Though round like the H6024, its smaller size means the two units are not interchangeable.
For 1977-1979 models, the high beam and low beam positions use different sealed beam types, H5001 and H5006 respectively, so the two positions require separate replacement units that are not cross-compatible with each other.
The 1973-1976 Audi Fox uses the H6024 for both high beam and low beam positions, which means a single sealed beam type covers both headlight functions across those years.
The shift from H6024 units to the H5001 and H5006 units occurred between the 1976 and 1977 model years, representing a change in both the shape and size of the sealed beam assemblies used across the headlight positions.
