The Nissan Cube front inner turn signal, front turn signal, and rear turn signal each require a PY21W bulb size, with 12496 as an alternative designation for certain positions. The replacement chart covers 2009 to 2014 model years and details bulb size specifications across vehicle production generations.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The PY21W is the most frequently specified bulb across the Nissan Cube turn signal positions. It follows the ECE standard used in Europe and worldwide markets, operates at 12V with a 21W output, uses a single filament, produces amber light, and seats into a BAU15s bayonet base.
The BAU15s base on the PY21W features an offset pin arrangement, which physically prevents installation of standard BA15s-based bulbs. This offset is a deliberate design feature to ensure correct polarity and amber-specific fitment.
The 12496 is a Philips/Osram part number designating a halogen bulb rated for specialty applications at 12V. It appears as an alternative to the PY21W in certain Nissan Cube model years across the front inner and rear turn signal positions.
The front turn signal position on the Nissan Cube uses the PY21W across all documented years from 2009-2014, with the 2009 entry specifying fitment from February 2009 onward.
The front inner turn signal position on the Nissan Cube alternates between the 12496 and PY21W across model years. The 2009, 2011, and 2013 model years specify the PY21W, while the 2010, 2012, and 2014 model years specify the 12496.
The rear turn signal position on the Nissan Cube specifies the PY21W for 2009-2013 model years, while the 2014 model year specifies the 12496 instead.
Because the 12496 and PY21W are not universally interchangeable despite sharing a 12V rating, the alternating specifications across model years of the Nissan Cube indicate that direct substitution between the two bulb types without confirming the specific model year would risk an incorrect fitment.
