Volkswagen Dasher headlight bulbs utilize H5001 and H6024 sizes for high beam applications, while low beam functions require H5006 and H6024 bulb sizes. The replacement chart covers 1974 through 1981 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volkswagen Dasher uses three sealed beam bulb types across its headlight system: H5001, H5006, and H6024. 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 housing. None of the three bulb types used on the Dasher accept a replaceable bulb; the entire sealed unit requires replacement when the light fails.
The H6024 is a 7-inch round sealed beam unit. On the Volkswagen Dasher, it served as both the high beam and low beam headlight for the 1974-1977 model years, functioning as a dual-purpose unit within a single housing.
Starting with the 1978 model year, the Dasher transitioned away from the H6024 to separate bulb types for each beam function. The high beam adopted the H5001 and the low beam adopted the H5006, a configuration that continued through 1981.
The H5001 is a 4-inch square sealed beam unit designated for high beam use on the 1978-1981 Dasher. Its square form factor is physically incompatible with the round housings used in earlier model years.
The H5006 is a 5.75-inch round sealed beam unit designated for low beam use on the 1978-1981 Dasher. Although it shares a round profile with the H6024, the two units are not the same size and are not interchangeable.
The shift from a single H6024 unit handling both beams to separate H5001 and H5006 units reflects a change in headlight housing design between the 1977 and 1978 model years. Parts sourced for one era of the Dasher are not compatible with the other.
