The Ferrari 512 TR uses 1156 bulb size for both front and rear turn signal applications. The replacement chart covers 1992 to 1994 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 the sole bulb type listed across all turn signal positions for the Ferrari 512 TR, covering model years 1992-1994.
The 1156 is a single-filament bulb, meaning it serves one lighting function per socket rather than combining two functions such as braking and signaling into a shared unit.
It operates on a 12-volt electrical system and draws 21 watts, which is consistent with standard automotive incandescent turn signal applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin offset to one side, ensuring the bulb seats in one orientation only.
The 1156 carries ANSI standardization applicable to the United States and Canada, placing it within a widely recognized specification framework for North American markets.
The Ferrari 512 TR uses the same 1156 bulb size for both the front and rear turn signals across all listed model years, indicating a uniform socket type throughout the vehicle's turn signal circuit.
The BA15s base of the 1156 is not interchangeable with the BA15d base found on dual-contact bayonet bulbs such as the 1157, as the pin configurations differ and the sockets are not compatible.
