The Suzuki Samurai brake light uses 1157 and 921 bulb sizes according to the provided technical data. Information for the specified components covers the period from 1986 through 1995.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Samurai brake light specifications reference two bulb types across its model years: the 1157 and the 921.
The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W/5W output. The dual-filament design allows it to serve both brake and tail light functions within a single housing.
The 921 is a single-filament wedge-type bulb in a T15 form factor, rated at 12V and 16W. Its wedge base requires no separate metal base, as the glass envelope itself acts as the retention mechanism.
Both the 1157 and 921 conform to ANSI standards applicable in the United States and Canada.
The Suzuki Samurai uses the 1157 for the brake light position in 1986 and again from 1990-1995, while the 921 is specified for 1987-1989.
Because the 1157 uses a BAY15d bayonet base and the 921 uses a wedge base, the two bulb types are not interchangeable despite both operating at 12V.
The center high mount stop light on the Samurai, covered for model years 1990-1995, uses the 921 wedge bulb exclusively across all listed years for that position.
For 1990-1995, the Samurai uses different bulb types depending on the light position: the 1157 for the standard brake light and the 921 for the center high mount stop light.
