Nissan Kicks Turn Signal Bulb Size

Additional Notes

• The 3457NA is the most frequently specified bulb across the Nissan Kicks turn signal positions. It is an ANSI-standard dual-filament T25 wedge bulb rated at 12V with a 27W main filament and a 7W secondary filament. Its natural amber glass produces the amber signal color without relying on a colored lens or housing.
• The 7440NA is a single-filament T20 wedge bulb rated at 12V and 21W. Unlike the dual-filament 3457NA, it carries only one filament, meaning it serves a dedicated turn signal function rather than a combined stop/turn role.
• The 3757NA shares the same T25 wedge form and natural amber glass construction as the 3457NA and carries the same ANSI designation structure, but its wattage rating is not specified in the available data.
• The 12961 is a Philips part number for a miniature T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. Its significantly lower wattage and smaller T10 form factor make it physically and electrically incompatible with the T25 and T20 sockets used in all other positions on the Kicks.
• For the Nissan Kicks front turn signal, the 2023 model year uses the 12961 rather than the 3457NA specified for the 2018-2020 and 2024 model years. Substituting a 3457NA into a 2023 front socket, or vice versa, would result in a fitment mismatch due to the difference in base type and bulb size.
• For the rear turn signal, the 2023 Nissan Kicks uses the 3757NA while the 2018-2020 model years use the 7440NA and the 2024 model year uses the 3457NA. All three are distinct bulb types, and none of these rear positions share a common specification across all listed years.
• The natural amber glass construction of the 3457NA, 3757NA, and 7440NA is denoted by the "NA" suffix in each designation. This coating is built into the glass envelope itself, distinguishing these bulbs from clear-glass equivalents such as the 3457, 3757, or 7440, which are not interchangeable where amber output is required by regulation.
• The 3457NA and 7440NA are both ANSI-standardized for the US and Canadian markets, meaning any manufacturer producing bulbs to those ANSI specifications will produce units with consistent electrical and physical characteristics, regardless of brand.
