The KYMCO Quannon 150 uses P21W bulb size for both front and rear turn signal applications. Replacement chart data covers 2010 to 2011 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 P21W is the sole bulb type across all turn signal positions on the KYMCO Quannon 150 for the 2010-2011 model years.
The P21W operates at 12 volts and consumes 21 watts, which is the standard wattage for single-filament automotive signalling applications.
The P21W uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin offset to one side of the base, preventing incorrect insertion.
The P21W is governed by ECE regulations, a certification framework recognized across Europe and numerous other markets worldwide.
Because the front and rear turn signals on the Quannon 150 share the same P21W specification, the bulbs are physically interchangeable between those positions.
The single-filament construction of the P21W means it serves one lighting function only, distinguishing it from dual-filament variants such as the P21/5W, which would not be a correct substitute.
