Additional Notes

The Kawasaki ZX1400 Ninja ZX-14R ABS SE uses two distinct bulb types across its front and rear turn signal positions: the 12496 and the PY21W. Both operate at 12 volts, making them compatible with the motorcycle's standard electrical system.
The 12496 is a halogen bulb designated for specialty applications and is identified by a Philips/Osram part number rather than a universal ECE or SAE standard code. Its voltage rating is 12V, though no wattage figure is specified in the provided data.
The PY21W follows the ECE standard used in Europe and worldwide markets. It is a single-filament amber bulb rated at 12V and 21W, fitted with a BAU15s offset bayonet base. The offset pin arrangement of the BAU15s base prevents incorrect installation by ensuring the bulb seats only in one orientation.
The BAU15s base on the PY21W is not interchangeable with the more common BA15s base. Sockets designed for one will not accept the other without modification, which is a relevant fitment consideration when replacing turn signal bulbs on affected model years.
For the front turn signal position, the 2016 Ninja ZX-14R ABS SE uses a PY21W, while the 2017-2018 model years use a 12496. This represents a direct bulb type change between the 2016 and 2017 model years in that position.
For the rear turn signal position, the 2017 model year uses a PY21W while both the 2016 and 2018 model years use a 12496. The front and rear positions do not share the same bulb type within every given model year, meaning the two positions require separate verification before replacement.
