The Chevrolet Sprint high beam and low beam headlight bulbs utilize a 9004 or H6054 bulb size for both functions. The replacement chart covers vehicle production spanning 1985 to 1987 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 Chevrolet Sprint's headlight specifications cover the 1985-1987 model years, with two distinct bulb types appearing across that range: the H6054 sealed beam unit for 1985-1986 and the 9004 halogen bulb for 1987.
The 9004 is a dual-filament halogen bulb operating at 12V, with a high beam output of 65W and a low beam output of 45W. Its P29t base is a single-contact bayonet-style connector specific to this bulb family.
Because the 9004 carries both filaments within a single housing, it serves both the high beam and low beam functions in the 1987 Sprint from one bulb position per side.
The H6054 is a 5x7-inch rectangular sealed beam unit rated at 12V. In a sealed beam design, the reflector, lens, and filament are fused into one glass assembly, meaning the entire unit is replaced rather than just an internal bulb.
The H6054 similarly handles both high beam and low beam duties in the 1985-1986 Sprint, as its specifications are listed identically under both sub-parts for those years.
Both the 9004 and H6054 conform to ANSI standards recognized in the United States and Canada, indicating compliance with North American photometric and dimensional requirements for automotive forward lighting.
The transition from the H6054 sealed beam to the 9004 halogen bulb between the 1986 and 1987 model years represents a change in headlight architecture, and the two types are not interchangeable with each other.
