Nissan Versa Turn Signal Bulb Size

Additional Notes

• The 7440NA bulb is a single-filament T20 wedge type rated at 12V and 21W, with natural amber glass that produces the amber turn signal color without a painted or coated lens. It serves as the rear turn signal bulb for the Nissan Versa across the 2021-2024 model years and also as the front turn signal bulb for the 2024 model year.
• The NA suffix found on several bulbs in these specifications, including the 7440NA, 7444NA, 2357NA, 3357NA, and 3457NA designations, indicates natural amber glass construction. This distinguishes them from their clear-glass counterparts, which share the same base numeric designation but lack the amber tint.
• The 7444NA and 7440NA bulbs share the same T20 wedge base, but the 7444NA is a dual-filament type rated at 21W/5W while the 7440NA is a single-filament type rated at 21W. These two bulbs are not interchangeable despite their physical similarity, as the dual-filament 7444NA has an additional contact point that the single-filament socket does not accommodate.
• The 3457NA and 3357NA bulbs both use the T25 wedge base, but the 3457NA is a dual-filament type rated at 27W/7W while the 3357NA is a single-filament type rated at 27W. The front turn signal positions for the 2013-2019 Versa alternate between these two designations across model years, meaning the filament count varies by year even within this generation.
• The PY21W bulb follows the ECE standard used in Europe and worldwide rather than the ANSI standard used in the United States and Canada. It uses a BAU15s bayonet base, which has offset pins at a 7.5-degree angle. This base is not compatible with the BAY15d bayonet base used on the 2357NA, making PY21W bulbs non-interchangeable with other bayonet-base bulbs in these specifications.
• The 12961 bulb listed for the 2020 Nissan Versa front turn signal is a Philips part number for a T10 miniature wedge type rated at only 12V and 5W. This wattage is substantially lower than all other front turn signal bulbs listed across the model range, which are rated between 21W and 27W.
• The 12496 designation is a manufacturer part number used by Philips and Osram rather than an ANSI or ECE standard code. It appears across multiple rear turn signal positions for the 2013-2014, 2016-2017, and 2019-2020 model years, and its voltage is specified at 12V in the provided data.
• The 2357NA uses a BAY15d bayonet base with dual filaments rated at 26.9W and 8W, making it the only bayonet-base ANSI bulb in these specifications. It is listed solely for the 2023 Nissan Versa front turn signal position, and its base type is physically distinct from the wedge bases used in all other front turn signal positions across the model range.
