Porsche 968 high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 1992 to 1995.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the specified size for both the high beam and low beam headlight positions on the Porsche 968 across all listed model years, 1992-1995.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
Because the 9003 serves both beam functions through its dual-filament design, the Porsche 968 uses the same physical bulb in a single headlight housing rather than separate bulbs for each beam mode.
The 9003 operates on a 12-volt electrical system, which is standard for passenger vehicles of this type.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 designation is an ANSI standard recognized in the United States and Canada. It is functionally equivalent to the international HB2 designation, though packaging and labeling may differ between markets.
