Toyota Tercel front and rear side marker bulbs utilize 1157, 194, and 168 bulb sizes depending on location and model configuration. The replacement chart covers vehicle production spanning 1980 to 1998 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Toyota Tercel front side marker uses three distinct bulb types across its production span: the 1157, 194, and 168. The rear side marker position is served exclusively by the 194 and 168 types.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W under the ANSI standard applicable in both the United States and Canada. It is a single-filament design with a wedge base that requires no rotation to seat.
The 168 shares the same T10 miniature wedge form factor as the 194 but operates at a higher wattage of 4.9W at 12V. Although the two bulbs are physically interchangeable in many sockets due to their shared base type, their wattage ratings differ and the specifications list them as distinct fitments for specific model years.
The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W main filament and a 5W secondary filament. Its dual-filament construction and bayonet base make it physically incompatible with the wedge sockets used by the 194 and 168.
The Toyota Tercel front side marker position specifies the 1157 for model years 1993-1998, representing a shift from the wedge-type bulbs used in earlier years. The BAY15d bayonet base of the 1157 is not interchangeable with the T10 wedge sockets found in other Tercel model years.
For the front side marker, the 168 is specified for 1988-1990, while the 194 covers 1980-1986 and 1991-1992. These three groups each require a different bulb, and substituting across groups without confirming socket compatibility is not supported by the specifications.
The rear side marker position uses the 194 for 1980-1992 and transitions to the 168 for 1993-1998. Both are T10 wedge bulbs, but their wattage values differ, and the specifications treat them as separate fitments rather than equivalents.
