The Toyota Paseo back up light utilizes 1156 and P21W bulb sizes for the rear illumination system. Data for the specified lighting components covers the range from 1992 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 is an ANSI-standardized bulb used in both the United States and Canada, operating at 12 volts with a 21-watt output and a single filament housed in a BA15s bayonet base.
The BA15s bayonet base features a single contact pin, which distinguishes it from dual-pin variants and makes it incompatible with sockets designed for double-contact bayonet bulbs.
The Toyota Paseo uses the 1156 bulb size across all back up light positions for the entire 1992-1998 model range.
A separate Outer Back Up Light position is specified for the 1995-1998 model years, also using the 1156 bulb.
The 1995 Outer Back Up Light specification carries a production cutoff of August 1995, indicating that this fitment applied only to vehicles produced up to that date within the model year.
