The Moto Guzzi Griso 1100 front turn signal requires a 5008 bulb size, while rear turn signals use either 232 or 5008 bulb sizes. The replacement chart covers 2005 through 2008 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 Moto Guzzi Griso 1100 uses two distinct bulb types across its turn signal positions: the 5008 and the 232, both conforming to ANSI standards applicable in the US and Canada.
The 5008 is a single-filament bulb with a BA15s bayonet base, operating at 12V. It is a lower wattage variant of the more widely known 1156 bulb, sharing the same base type but drawing less power.
The 232 is a festoon bulb with an SV8.5 base, rated at 12V and 3W. Festoon bulbs are cylindrical in form and seat by contact pressure at each end rather than by a twist or push-in base.
The front turn signal position on the Griso 1100 uses the 5008 bulb across all documented model years, spanning 2005-2008.
The rear turn signal position uses the 232 bulb for model years 2006-2008.
For the 2005 model year, the Griso 1100 rear turn signal also uses the 5008 bulb, making both front and rear positions identical for that year.
The BA15s base of the 5008 is a single-contact bayonet fitting. It is not interchangeable with the BA15d double-contact bayonet base found on some other automotive bulbs, despite the similar physical appearance.
The SV8.5 base of the 232 festoon bulb refers to the 8.5mm width of the end caps. Festoon bulbs of differing lengths are not interchangeable even when they share the same base designation, as fitment depends on the length of the housing cavity.
