Additional Notes

The H3 bulb is the specified front fog light fitment for the Toyota MR2 across the 1993-1995 model years.
The H3 is a single-filament halogen bulb operating at 12 volts and 55 watts, mounted on a PK22s base. The PK22s base uses a pinch-style connection, which differs from the bayonet or wedge bases found on other automotive bulb types, making cross-substitution with those types incompatible.
The H3 carries ECE certification, meaning it meets the regulatory standards applied across Europe and much of the wider world, and it also holds approval for use in the United States and Japan.
Because the H3 is a single-filament bulb, it serves one lighting function only. It is not interchangeable with dual-filament bulbs such as the H4, which combine two circuits within a single housing.
