The Maserati Spyder front and rear turn signal bulbs both utilize a 1156 size bulb for proper operation. The replacement chart covers vehicle production spanning 1986 to 1991.
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 specified for both the front and rear turn signals of the Maserati Spyder across all listed model years.
The 1156 is a single-filament bulb, meaning it is dedicated to one lighting function rather than serving dual purposes such as combined stop and turn signal operation.
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 bayonet mount that differs from the dual-contact BA15d base found on two-filament bulbs such as the 1157.
The BA15s base design means the 1156 is not interchangeable with dual-filament bayonet bulbs, as the contact configuration is physically distinct.
The 1156 carries ANSI standardization applicable in both the United States and Canada, indicating a consistent specification across North American markets.
The same 1156 specification applies to both the front and rear turn signal positions on the Maserati Spyder for the years 1986-1987 and 1989-1991.
