Additional Notes

The H3 is a single-filament halogen bulb operating at 12 volts and 55 watts, built to the ECE standard used across Europe and worldwide, with approval also extended to the United States and Japan. Its base type is PK22s, a single-pin base where the pin is centered and surrounded by a metal skirt that locks into the socket.
The Toyota Previa front fog light uses the H3 bulb size across the 1995-1997 model years, though the 1997 application is noted as valid only through July 1997.
All listed fitments are restricted to vehicles equipped with an Electronic Fuel Injection system, meaning the H3 fog light specification does not apply to Previa variants outside that configuration.
The mid-year cutoff noted for 1997, ending in July of that year, indicates a production change occurred within the model year, after which the H3 specification for the front fog light no longer applies.
The PK22s base is not interchangeable with other common halogen bases such as H1 or H7, which use different pin and socket configurations, making base-type verification essential before substitution.
