Suzuki Motorcycle DL650A V-Strom XT ABS Turn Signal Bulb Size

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.
