Moto Guzzi California Stone Touring Turn Signal Bulb Size
Moto Guzzi California Stone Touring front and rear turn signal bulbs utilize a 5008 size specification. The replacement chart covers 2004 to 2005 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 5008 is the sole bulb type specified for the Moto Guzzi California Stone Touring across both front and rear turn signal positions for the 2004-2005 model years.
The 5008 follows the ANSI standard, meaning it conforms to a defined North American specification used in the United States and Canada.
It is a single-filament bulb, which means it serves one lighting function only, as opposed to dual-filament bulbs that handle two functions such as running light and turn signal simultaneously.
The 5008 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and twisted to lock into place.
The 5008 operates at 12 volts, consistent with the standard electrical systems found in most motorcycles of this era.
The 5008 is a lower wattage variant of the 1156 bulb, meaning both share the BA15s bayonet base and general form but differ in power output, which makes them non-interchangeable despite their physical similarities.
Because the 5008 and 1156 share the same base type, a 1156 could physically fit the California Stone Touring's turn signal sockets, but the higher wattage of the 1156 would not match the original specification.
