Honda Motorcycle VT1300CR Stateline Turn Signal Bulb Size
Honda Motorcycle VT1300CR Stateline front turn signal bulb uses P21/5W size while rear turn signal bulb uses P21W size. Replacement chart covers 2010 to 2016 model 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 Honda Motorcycle VT1300CR Stateline uses two distinct turn signal bulb types across its front and rear positions, with the front and rear positions requiring different bulbs that are not interchangeable with each other.
The front turn signal on the VT1300CR Stateline uses the P21/5W bulb across the 2010-2016 model years.
The P21/5W is a dual-filament bulb rated at 12V with a 21W main filament and a 5W secondary filament, mounted on a BAY15d bayonet base.
The BAY15d base on the P21/5W features offset pins, a physical design that prevents accidental installation of single-filament bulbs in dual-filament sockets.
The rear turn signal on the VT1300CR Stateline uses the P21W bulb across the 2010-2016 model years.
The P21W is a single-filament bulb rated at 12V and 21W, mounted on a BA15s bayonet base.
The BA15s base on the P21W features symmetrically placed pins, which is mechanically incompatible with the offset-pin BAY15d socket used by the front turn signal.
Both the P21/5W and P21W conform to ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide.
Although both bulbs share a 21W signalling filament output, the P21/5W and P21W are not interchangeable due to their differing base configurations and filament counts.
