The Triumph Street Cup uses 232 bulb size for both front and rear turn signal applications. Replacement specifications in the chart cover 2017 to 2018 model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 232 bulb is the sole bulb type specified across all turn signal positions on the Triumph Street Cup for the 2017-2018 model years.
The 232 bulb follows the ANSI standard, which is the American National Standards Institute classification system used to designate bulb types in the United States and Canada.
It is a festoon-style bulb, meaning it is cylindrical in form and held in place at both ends by spring-loaded contacts rather than a screw or bayonet base.
The 232 uses an SV8.5 base, which refers to the 8.5mm contact cap width at each end of the festoon body.
The bulb operates at 12 volts and draws 3 watts, placing it in the low-wattage range typical of indicator and auxiliary lighting applications.
The same 232 bulb specification applies to both the front and rear turn signal positions, indicating that the two positions share a common fitment requirement.
