The Buell XB12X Ulysses front turn signal bulb measures 5008 or 232 in size, while the rear turn signal bulb measures 5008 in size. The replacement chart covers 2006 through 2009 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 the most widely used bulb type across the Buell XB12X Ulysses turn signal specifications, appearing in both front and rear positions across multiple model years.
The 5008 is an ANSI-standard single-filament bulb operating at 12V, fitted with a BA15s bayonet base, and is classified as a lower wattage variant of the 1156 bulb.
The 232 is an ANSI-standard festoon bulb rated at 12V and 3W, fitted with an SV8.5 base, representing a physically and electrically distinct type from the 5008.
The BA15s bayonet base of the 5008 and the SV8.5 festoon base of the 232 are not interchangeable, as each requires a different socket type for installation.
The rear turn signal position on the Buell XB12X Ulysses uses the 5008 bulb across all four model years covered in the specifications, from 2006-2009.
The front turn signal position does not use a single bulb type across all years. The 2007-2008 front position specifies the 232 festoon bulb, while 2006 and 2009 specify the 5008.
A vehicle owner sourcing front turn signal bulbs for a 2007 or 2008 Buell XB12X Ulysses would require the 232 festoon type rather than the 5008 bayonet type used in other years.
Both the 5008 and 232 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and dimensional specifications within those markets.
