Additional Notes

The P21W bulb, used in both front and rear turn signals on the Suzuki Motorcycle DL650A V-Strom XT ABS for 2015-2016, is an ECE-standard single-filament signalling bulb rated at 12V and 21W, fitted with a BA15s bayonet base.
The PY21W bulb, which appears in the 2018 front turn signal position, is also an ECE-standard single-filament bulb rated at 12V and 21W, but it produces amber light natively and uses a BAU15s bayonet base rather than the BA15s base found on the P21W.
The BAU15s base of the PY21W and the BA15s base of the P21W are physically offset differently, making these two bulb types non-interchangeable despite sharing the same voltage and wattage ratings.
The 12496 designation is a Philips/Osram part number for a 12V halogen bulb intended for specialty applications, and it is used in the 2017 front turn signal, the 2017 rear turn signal, and the 2018 rear turn signal positions.
The front turn signal socket of the DL650A V-Strom XT ABS required three distinct bulb types across the 2015-2018 model years, with P21W fitted for 2015-2016, 12496 for 2017, and PY21W for 2018.
The rear turn signal positions for 2015-2016 use the P21W, while 2017-2018 rear positions both use the 12496, indicating a change in rear fitment between the 2016 and 2017 model years.
Because the 2017 and 2018 model years share the 12496 bulb in the rear turn signal position but differ in the front, a replacement purchase requires the position of the bulb to be confirmed before selecting a part.
