The Honda Prelude brake light utilizes 7443, 3496, and 2057 bulb sizes depending on the specific generation of the vehicle. Available data covers the range from 1979 to 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Prelude brake bulb specifications cover three distinct bulb types across the main brake light position: the 2057 for 1979-1990, the 3496 for 1992-1996, and the 7443 for 1997-2001.
The 7443 is a dual-filament wedge bulb in the T20 form factor, rated at 12V with a 21W high filament and 5W low filament, conforming to ANSI standards for the US and Canada markets.
The 3496 uses a BAY15d bayonet base and is a dual-filament bulb described as a variant of the 1157, operating at 12V. The 2057 also uses a BAY15d bayonet base and is described as a brighter variant of the 1157, rated at 12V with 26.9W and 8W filaments.
Although the 3496 and 2057 share the same BAY15d bayonet base type, they are specified as separate part numbers and are not listed as interchangeable within these specifications.
The Center High Mount Stop Light on the Honda Prelude also transitions across three bulb types: the 1156 for 1986-1991, the 921 for 1992-1996, and the 7440 for 1997-2001.
The 7440 is a single-filament T20 wedge bulb rated at 12V and 21W. It shares the same T20 wedge form factor as the 7443 but differs in that it carries only a single filament, making the two bulbs non-interchangeable despite their physical similarity.
The 921 is a single-filament wedge bulb in the smaller T15 form factor, rated at 12V and 16W, and is not physically compatible with the T20 socket used by the 7440 or 7443.
The 1156 uses a BA15s single-contact bayonet base, rated at 12V and 21W. Its base type differs from the BAY15d base found on the 2057 and 3496, meaning these bulbs are not interchangeable despite similar voltage ratings.
The Outer Brake sub-part position on the Honda Prelude (1997-2001) specifies the 7443, the same dual-filament T20 wedge bulb used in the main brake position for those same years.
All bulb types listed across the Honda Prelude brake specifications conform to ANSI standards applicable to the US and Canadian markets.
