Toyota Previa Parking Light Bulb Size

The Toyota Previa parking light uses 1157NA, 1034NA, and 1157 bulb sizes depending on the specific version of the vehicle. Data for the bulb sizes covers the range from 1991 to 1997.

Additional Notes

The Toyota Previa parking light specifications cover model years 1991-1997 and reference three bulb types: 1157, 1157NA, and 1034NA.
All three bulb types share the BAY15d bayonet base and a dual-filament design rated at 12V with a 21W/5W power split, where the higher wattage filament serves the main function and the lower wattage filament serves a secondary role.
The 1157NA and 1034NA types feature natural amber glass, which produces an amber-colored output without the need for an external amber lens or filter. The standard 1157 has no such glass tint.
The 1034NA is classified as a variant of the 1157, sharing the same voltage and wattage ratings. Despite this relationship, the two carry distinct ANSI designations and are listed separately in the specifications.
The Toyota Previa (1991-1992) uses the 1157, while the 1993-1995 model years use the 1034NA, and the 1996-1997 model years use the 1157NA. This means the parking light bulb type changed twice across the production run covered by these specifications.
Because the 1034NA and 1157NA are distinct ANSI designations from the 1157, substituting one for another without confirming fitment compatibility carries a risk of incorrect function, even though the electrical ratings are identical across all three types.
All three bulb types conform to ANSI standards applicable in both the United States and Canada, indicating they are designed for North American market vehicles.
