Suzuki Motorcycle DL1000 V-Strom Turn Signal Bulb Size

Additional Notes

• The two bulb types specified across the Suzuki Motorcycle DL1000 V-Strom turn signal positions are 12496 and PY21W. Both operate at 12 volts, making them electrically compatible in that regard, though they are not interchangeable due to differences in base type and standardization origin.
• The PY21W is defined by the ECE standard and is recognized internationally. It uses a BAU15s offset bayonet base, is single-filament, and produces amber light at 21 watts. The offset pin arrangement of the BAU15s base physically prevents installation of non-amber bulbs in sockets designed for it.
• The 12496 is a halogen bulb designated under Philips and Osram part numbering systems for specialty applications, rated at 12 volts. It does not carry an ECE designation in the provided specifications.
• Front turn signal fitment on the DL1000 V-Strom is not uniform across all listed years. The 2015-2016 model years use PY21W at the front position, while the 2014 and 2018-2019 model years use 12496 at the same position.
• Rear turn signal fitment similarly varies by year. The 2014 model year uses PY21W at the rear, whereas the 2015-2016 and 2018-2019 model years use 12496 at the rear position.
• In 2015 and 2016, the front and rear turn signal positions use different bulb types from each other, with PY21W at the front and 12496 at the rear. This means a single bulb type does not serve both positions on those model years.
• In 2014, the front position uses 12496 while the rear uses PY21W, again resulting in a split fitment where the two positions require different bulb types.
• The 2018-2019 model years are the only ones in the specifications where both the front and rear turn signal positions share the same bulb type, with 12496 specified at both locations.
