Additional Notes

The H3 bulb is the specified front fog light fitment for the Pontiac G3 across the 2009-2010 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 is a pinch-base connector, distinguishing the H3 from screw-base or bayonet-style automotive bulbs and making it non-interchangeable with those types.
The H3 carries ECE certification, meaning it meets the regulatory standards used across Europe and much of the world, and it also holds approval for use in the United States and Japan.
