The Ferrari F355 Spider front and rear turn signal bulbs both utilize a 1156 size bulb for replacement applications. The replacement chart covers 1996 to 1999 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 1156 is a single-filament bulb rated at 12 volts and 21 watts, built on a BA15s bayonet base, which uses a single contact pin offset to one side to ensure correct orientation during installation.
The BA15s base designation distinguishes the 1156 from double-contact bayonet bulbs such as the 1157, meaning the two types are not interchangeable despite sharing a similar physical form.
The Ferrari F355 Spider uses the 1156 bulb for both the front and rear turn signals across all model years covered in the specifications, spanning 1996-1999.
Because the same bulb type is specified for both front and rear positions, a single 1156 bulb serves both locations without variation by position or year.
The 1156 carries ANSI standardization recognized in both the United States and Canada, placing it within a regulated specification for electrical and photometric performance.
At 21 watts, the 1156 falls within the range typical for turn signal applications, where sufficient light output is required for visibility under daylight conditions.
