The Ferrari 348 Spider uses a 9005 bulb size for high beam headlight operation and a 9006 bulb size for low beam headlight operation. The replacement chart covers 1993 to 1995 model 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 348 Spider uses the 9005 bulb for high beam headlights across the 1993-1995 model years.
The 9005 is a single-filament halogen bulb operating at 12V and 65W, built to the ANSI standard for the US and Canadian markets, and fitted with a P20d base.
Low beam headlights on the 348 Spider use the 9006 bulb across the same 1993-1995 model years.
The 9006 is also a single-filament halogen bulb rated at 12V but draws 55W rather than 65W, and it uses a P22d base rather than the P20d base found on the 9005.
Because the 9005 and 9006 share a similar body style but carry different base types, P20d and P22d respectively, the two bulbs are not physically interchangeable despite their close wattage ratings.
The wattage difference between the two bulbs, 65W for high beam and 55W for low beam, reflects a standard design practice in halogen headlight systems where the high beam filament draws more power to produce greater output.
Both bulbs conform to ANSI standards, meaning their electrical and physical specifications are governed by a defined North American industry standard rather than a manufacturer-specific design.
