Ferrari F355 GTS headlight bulbs utilize 9005 size for high beam and 9006 size for low beam applications. The replacement chart covers 1994 to 1998 model production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ferrari F355 GTS uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across all model years from 1994-1998.
Both the 9005 and 9006 are ANSI-standardized halogen bulb types recognized in the United States and Canada, each operating on a 12-volt electrical system.
The 9005 is a single-filament halogen bulb rated at 65 watts, fitted with a P20d base, and serves the high beam function in the F355 GTS.
The 9006 is a single-filament halogen bulb rated at 55 watts, fitted with a P22d base, and serves the low beam function. Its lower wattage relative to the 9005 reflects the reduced output typical of low beam applications.
Although the 9005 and 9006 share a similar physical profile, their base types differ: the P20d base of the 9005 and the P22d base of the 9006 are not interchangeable. Installing one in place of the other is not supported by these specifications.
