The Suzuki X-90 brake light requires a 1157 bulb size for proper installation and function. Data for the specified vehicle covers the range from 1996 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki X-90 uses the 1157 bulb for brake lights across the 1996-1998 model years.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, typically stop and tail light operation.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect installation by ensuring only one rotational orientation fits the socket.
The 1157 operates at 12V and draws 21W on the high-intensity filament and 5W on the low-intensity filament.
The center high mount stop light on the Suzuki X-90 uses the 168 bulb across the 1996-1998 model years.
The 168 is a T10 miniature wedge bulb, a single-filament design that seats directly into a wedge-style socket without a separate base or pins.
The 168 operates at 12V and draws 4.9W, reflecting its role as a low-power indicator rather than a primary brake light source.
Both the 1157 and 168 conform to ANSI standards applicable in the United States and Canada.
The 1157 and 168 are not interchangeable with each other, as they differ in base type, wattage, filament count, and socket fitment.
