Toyota Solara Parking Light Bulb Size

The Toyota Solara parking light requires bulb size 1157NA or 1034NA depending on the specific version of the lighting component. Data for the bulb sizes covers the range from 1999 to 2003.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

Both the 1157NA and 1034NA are ANSI-standard dual-filament bulbs operating at 12V with a 21W/5W power split, where the higher wattage filament serves the primary function and the lower wattage filament serves a secondary role such as running light operation.
Both bulb types share the BAY15d bayonet base, a two-pin offset base design in which the two pins are positioned at different heights to prevent incorrect insertion.
The natural amber glass in both the 1157NA and 1034NA produces a yellow-orange tint directly from the glass envelope rather than from a coating or lens, which is the defining characteristic of the "NA" designation in each part number.
The 1034NA is described as a variant of the 1157, meaning the two types share the same base and general construction but differ in filament output characteristics, which makes them non-interchangeable despite their physical similarities.
The Toyota Solara (2000-2002) uses the 1034NA for its parking light, while the 1999 and 2003 model years use the 1157NA, reflecting a fitment split across the production run.
Because the 1034NA and 1157NA share the BAY15d base, one could physically seat in a socket intended for the other, making it important to match the exact part number rather than relying on physical fit alone.
