Triumph Thruxton 1200 front and rear turn signal bulbs both utilize a 232 size bulb specification. The replacement chart covers vehicle production spanning 2016 to 2018.
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 turn signal bulb type used across all listed positions and years for the Triumph Thruxton 1200, covering both front and rear turn signals for the 2016-2018 model years.
The 232 is a festoon-style bulb, meaning it is cylindrical in shape and held in place by contact clips at each end rather than a screw or bayonet base.
It uses an SV8.5 base, which refers to the 8.5mm contact cap at each end of the festoon body. This base type is a defining factor in physical fitment and must match the socket in the housing.
The 232 operates at 12 volts and draws 3 watts, placing it in the low-wattage range typical of indicator and auxiliary lighting applications on 12V electrical systems.
The 232 conforms to ANSI standards as recognized in the United States and Canada, meaning its electrical and physical characteristics follow a defined North American specification.
Because the Thruxton 1200 uses the same 232 bulb in all four turn signal positions, front and rear sockets share the same fitment requirement, and the bulbs are interchangeable between positions.
Any replacement bulb intended for these sockets must match the SV8.5 festoon base, 12V rating, and 3W output to maintain correct fitment and circuit compatibility.
