Moto Guzzi California Classic Touring Turn Signal Bulb Size
Moto Guzzi California Classic Touring front turn signal bulbs use 5008 size, while rear turn signal bulbs use 5008 or 232 size. The replacement chart covers 2006 to 2007 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 5008 is a single-filament bulb with a BA15s bayonet base, operating at 12V. It is classified as a lower wattage variant of the 1156 under the ANSI standard used in the US and Canada.
The BA15s base designation indicates a single-contact bayonet fitting with a 15mm base width, which is not interchangeable with dual-contact BA15d bases used in some other automotive applications.
The 232 is a festoon-style bulb with an SV8.5 base, rated at 12V and 3W under the same ANSI standard. Festoon bulbs are cylindrical in form and seat by contact pressure at each end rather than through a twist-lock or bayonet mechanism.
The SV8.5 base on the 232 bulb refers to a festoon holder with an 8.5mm width, and it is not physically compatible with BA15s sockets used by the 5008.
On the Moto Guzzi California Classic Touring, the front turn signal position uses the 5008 bulb for both the 2006 and 2007 model years.
The rear turn signal position differs between model years. The 2007 model uses the 5008, while the 2006 model uses the 232, meaning the two years do not share the same rear turn signal bulb type.
Because the rear turn signal bulb types differ between 2006 and 2007, a direct substitution between model year components at the rear position would require confirming socket compatibility before installation.
The 2007 model year uses the 5008 in all four turn signal positions, front and rear, making it the sole bulb type required for that year's turn signal circuit.
