Honda Pilot Trunk Bulb Size

The Honda Pilot trunk requires a 7440NA or 12961 bulb size depending on the specific version required for the vehicle. Data for the provided specifications covers the range from 2021 to 2024.

Additional Notes

The Honda Pilot uses two distinct bulb types across its trunk bulb specifications: the 7440NA and the 12961, each belonging to different size families with incompatible bases.
The 7440NA is a T20 single-filament wedge bulb rated at 12V and 21W. Its natural amber glass is a defining physical characteristic that distinguishes it from clear variants in the same T20 family.
The 12961 is a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It is referenced under a Philips part number rather than an ANSI designation.
The T20 and T10 form factors are physically incompatible. The W2.1x9.5d base of the T10 (12961) cannot be substituted into a socket designed for the larger T20 wedge base of the 7440NA, and vice versa.
The 7440NA carries an ANSI standard designation applicable in the United States and Canada, meaning it conforms to a standardized specification shared across multiple manufacturers rather than being proprietary to a single brand.
The 2023-2024 Honda Pilot uses the 7440NA for the trunk bulb position, while the 2021 model uses the 12961, indicating a difference in socket type between these model year groups.
The wattage difference between the two bulb types is significant: the 7440NA draws 21W compared to the 12961 at 5W, reflecting their different roles and socket electrical ratings rather than a simple substitution relationship.
