The Toyota Paseo front turn signal requires a 1157, 1034NA, or 1157NA bulb size, while the rear turn signal uses a 1156 bulb size. The replacement chart covers vehicle production years spanning 1992 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Toyota Paseo uses three distinct front turn signal bulb types across its 1992-1998 production span: the 1157, the 1157NA, and the 1034NA, while the rear turn signal position uses the 1156 uniformly across all seven model years.
The 1157 is a dual-filament bulb operating at 12V with a 21W/5W output split, mounted on a BAY15d bayonet base. The dual-filament design allows a single bulb to serve both a high-intensity signaling function and a lower-intensity running or parking light function simultaneously.
The 1157NA and 1034NA are natural amber glass variants that produce an amber color through the glass itself rather than through a colored lens or housing. Both share the same BAY15d bayonet base and 12V, 21W/5W electrical ratings as the standard 1157.
The 1034NA is noted as a variant of the 1157, meaning the two share the same base type and wattage ratings, though the natural amber coating distinguishes the 1034NA from the clear-glass 1157.
The front turn signal position on the Toyota Paseo (1994-1995) specifies the 1034NA, while the 1993 model year specifies the 1157NA. Both are amber glass dual-filament bulbs with BAY15d bases, but they carry different ANSI designations.
The 1156 rear turn signal bulb is a single-filament unit rated at 12V and 21W, fitted with a BA15s bayonet base. The BA15s base is not interchangeable with the BAY15d base used by the dual-filament front turn signal bulbs, as the two base types differ in pin offset configuration.
Substituting a single-filament 1156 for a dual-filament 1157-series bulb in the front position would result in the loss of one filament's function, as the socket is wired to engage both filaments independently.
All bulb types listed across both positions conform to ANSI standards applicable to the United States and Canada, indicating standardized dimensional and electrical tolerances across the 1157, 1034NA, 1157NA, and 1156 designations.
