Honda Motorcycle GL1500 Gold Wing uses 24 bulb size for inner tail light and 2057 bulb size for outer tail light. The replacement chart covers 1988 to 1990 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 Honda Motorcycle GL1500 Gold Wing uses two distinct tail light bulb types across its 1988-1990 model years: the 24 for the inner tail light position and the 2057 for the outer tail light position.
The 24 bulb is an ANSI-standard single-filament type rated at 12V and 2W, fitted with a BA9s miniature bayonet base, which is a small single-pin base commonly associated with low-wattage indicator and marker applications.
The 2057 bulb is an ANSI-standard dual-filament type rated at 12V with a high-filament draw of 26.9W and a low-filament draw of 8W, reflecting its function across both brake light and running light circuits.
The 2057 uses a BAY15d base, a bayonet-style two-pin base with offset pins that prevent incorrect insertion orientation, a design feature that distinguishes it from single-filament bayonet bases.
The 2057 is noted as a brighter variant of the 1157, meaning the two share the same BAY15d base and are physically interchangeable in terms of fitment, though the 2057 draws more current on its high-filament circuit.
Because the 2057 draws higher wattage than the 1157 on the high filament, substituting one for the other in the GL1500 Gold Wing outer tail light position may affect brightness output relative to the original specification.
Both the 24 and 2057 are classified under ANSI standards applicable to the US and Canadian markets, indicating these specifications reflect North American market variants of the GL1500 Gold Wing.
The inner and outer tail light positions on the GL1500 Gold Wing are not interchangeable with each other, as the 24 and 2057 use entirely different base types, BA9s and BAY15d respectively, making cross-position substitution physically incompatible.
