Description	Bulb Size
ECE standard (Europe & worldwide). Single-filament halogen bulb with PK22s base. Also approved in the US and Japan. 12V, 55W.	H3

The Honda Prelude front fog light takes the H3 bulb across all listed model years, spanning 1988-1991 and 1995-2001.
The H3 is a single-filament halogen bulb, meaning it contains one tungsten filament enclosed in a halogen gas-filled quartz envelope, which allows for a higher operating temperature and greater light output relative to standard incandescent bulbs of the same wattage.
H3 bulbs operate at 12 volts and 55 watts, which are standard ratings for halogen fog lighting in passenger vehicles.
The H3 uses a PK22s base, a pinch-base connector where the electrical contacts are integrated into the flattened glass pinch at the bottom of the bulb rather than a screw or bayonet fitting.
The H3 is an ECE-regulated bulb type, meaning it conforms to the Economic Commission for Europe lighting standards, which govern photometric output, color temperature, and safety requirements across European and many worldwide markets.
Despite its ECE origins, the H3 also holds approval for use in the United States and Japan, making it one of the more broadly accepted halogen fog light types across major automotive markets.
Because the PK22s base is specific to the H3 format, bulbs with different base types are not physically interchangeable with the Honda Prelude front fog light housing without modification.
