Toyota Solara Turn Signal Bulb Size

Toyota Solara front turn signal bulbs use 1034NA or 1157NA sizes, while rear turn signal bulbs use 2356, 3156, or 3157NA sizes. The replacement chart covers 1999 to 2003 model years with corresponding bulb size specifications.

Additional Notes

The Toyota Solara front turn signal uses two distinct bulb types across its model years: the 1034NA for 1999 and 2003, and the 1157NA for 2000-2002. Both are dual-filament bulbs rated at 12V, 21W/5W, and both share the BAY15d bayonet base, with the 1034NA classified as a variant of the 1157NA.
The natural amber glass designation on the 1034NA and 1157NA bulbs indicates that the amber color is produced by the glass envelope itself rather than by a colored lens housing. This is reflected in the "NA" suffix, which stands for natural amber.
Although the 1034NA and 1157NA share the same BAY15d base and wattage ratings, they are distinct ANSI part numbers and are not universally interchangeable without confirming fitment for the specific model year of the Toyota Solara.
The rear turn signal of the Toyota Solara uses three different bulb types across its model years: the 3157NA for 1999-2001, the 3156 for 2002, and the 2356 for 2003. Each of these represents a separate ANSI specification.
The 3157NA, used in the rear turn signal for 1999-2001, is a dual-filament T25 wedge bulb rated at 12V, 27W/7W, with natural amber glass. The 3156, used for 2002, is a single-filament T25 wedge bulb rated at 12V, 27W, making it functionally distinct from the dual-filament 3157NA despite sharing the same T25 form factor.
The single-filament design of the 3156 means it operates only at one brightness level, whereas the dual-filament 3157NA supports two brightness levels, typically used for combined turn signal and running light functions. Substituting one for the other in the Toyota Solara rear turn signal position would not be a direct equivalent swap.
The 2356 rear turn signal bulb used in the 2003 Toyota Solara carries a BAY15d bayonet base, which differs from the T25 wedge base found on the 3156 and 3157NA bulbs used in prior model years. This base type difference makes the 2356 physically incompatible with sockets designed for the wedge-style bulbs used in 1999-2002.
All bulb types listed across both the front and rear turn signal positions conform to ANSI standards applicable to the United States and Canada, indicating standardized electrical and mechanical specifications within those markets.
