The Toyota T100 tail light requires a 1157 bulb size for proper installation and function within the rear lighting assembly. Data for the specified component covers the range from 1993 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1157 bulb is the sole bulb type specified for the outer tail lights of the Toyota T100 across all listed model years.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, typically combining stop light and tail light operation at different brightness levels.
It operates on a 12-volt electrical system and draws 21 watts on the high-filament circuit and 5 watts on the low-filament circuit, reflecting its dual-intensity design.
The 1157 uses a BAY15d bayonet base, which features two offset pins that prevent incorrect insertion and ensure consistent filament alignment within the housing.
The bulb conforms to ANSI standards and is rated for use in both the United States and Canada, indicating compliance with North American automotive lighting requirements.
The outer tail light position on the Toyota T100 used the 1157 bulb consistently across the 1993-1998 model years.
The BAY15d base is not universally interchangeable with other bayonet base types, such as the single-pin BA15s, and substitution with a different base type would result in an incompatible fit.
