Additional Notes

The H3 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PK22s base. The PK22s is a pinch-base connector, where the base is formed by a flattened glass pinch rather than a screw or bayonet fitting.
The H3 bulb follows the ECE (Economic Commission for Europe) standard, which governs bulb geometry, light output, and performance tolerances. Despite its European origin, the H3 carries approval for use in the United States and Japan as well.
The Chevrolet Beretta uses the H3 bulb across all four model years covered in the front fog light specifications, spanning 1991-1994.
The PK22s base type is not interchangeable with other common halogen bases such as H1 (P14.5s) or H4 (P43t). A bulb with a different base cannot be seated correctly in an H3 housing, making base compatibility a critical factor in replacement.
