Additional Notes

The H3 bulb is the sole front fog light bulb type listed for the Chevrolet Corsica across the 1994-1996 model years.
The H3 is a single-filament halogen bulb, meaning it serves one lighting function only and contains no secondary filament for alternate modes such as high or low beam switching.
H3 bulbs use a PK22s base, which is a pinch-base connector design rather than a bayonet or screw-type fitting, requiring a compatible socket of that specific base type.
The H3 operates at 12 volts and 55 watts, which are standard values for halogen fog lighting in passenger vehicles of that era.
The H3 is an ECE-standard bulb, meaning it conforms to the Economic Commission for Europe regulations governing automotive lighting, and it also carries approval for use in the United States and Japan.
Because the H3 carries multi-regional approval, the same bulb specification applies regardless of whether a replacement unit is sourced from a European, North American, or Japanese supplier, provided it meets the 12V, 55W and PK22s base criteria.
The PK22s pinch base is specific to the H3 and is not shared with other common halogen types such as H1 or H7, making those bulbs physically incompatible with the Corsica front fog light socket despite similar wattage ratings.
