The Ferrari F355 Spider uses a 9005 bulb size for high beam headlights and a 9006 bulb size for low beam headlights. The replacement chart covers 1996 to 1999 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 F355 Spider uses the 9005 bulb for high beam headlights across all documented model years, 1996-1999.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, built to ANSI standards for the US and Canadian markets, and fitted with a P20d base.
Low beam headlights on the F355 Spider use the 9006 bulb across the same 1996-1999 model year range.
The 9006 is also a single-filament halogen bulb operating at 12V but draws 55W, making it 10W lower in power than the 9005, and it uses a P22d base rather than the P20d found on the 9005.
The P20d base on the 9005 and the P22d base on the 9006 are physically distinct, meaning the two bulb types are not interchangeable despite their otherwise similar construction and voltage rating.
Both the 9005 and 9006 are governed by ANSI standards, which define consistent electrical and physical parameters for bulbs sold in the United States and Canada.
