The Toyota Previa tail light requires a 1157 bulb size for the specific lighting component located at the rear of the vehicle. Data for the bulb covers the range from 1991 to 1997.
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 across all outer tail light positions for the Toyota Previa, covering model years 1991-1997.
The 1157 is an ANSI-standard dual-filament bulb rated at 12 volts, with filaments drawing 21 watts and 5 watts respectively, allowing it to serve both stop and running light functions within a single unit.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect insertion by positioning its two pins at different heights along the base.
The 1997 outer tail light carries a production cutoff notation of "To 07/1997," indicating that the 1157 fitment applies only to vehicles produced through July of that year.
Single-filament substitutes such as the 1156 are not interchangeable with the 1157, as the BAY15d base is physically distinct from the single-filament BA15s base and the differing pin offsets prevent cross-fitting.
