The Nissan TITAN brake light utilizes bulb sizes 12177 and 3157 and 2458 for various configurations. Available information covers the specific time range from 2004 through 2023.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan TITAN uses two bulb types across its brake light positions: the 12177 and the 3157. Both operate at 12V and serve the main brake light function, though they are not interchangeable with each other.
The 3157 is an ANSI-standard dual-filament T25 wedge bulb rated at 12V with a 27W/8W output split, making it suitable for combined stop and tail light functions within a single housing.
The 12177 is a Philips part number designation for a 12V halogen bulb intended for specialty automotive applications. It does not carry an ANSI standardized number, which may affect cross-brand substitution.
The Nissan TITAN (2004-2015) uses the 3157 bulb for the main brake light position, while the 2017-2023 model years use the 12177 in that same position.
The center high mount stop light on the Nissan TITAN uses either the 912 or the 921 bulb, both of which are T15 wedge-type bulbs operating at 12V. Despite their physical similarity, they differ in wattage: the 912 is rated at 12W and the 921 at 16W.
The 912 and 921 are both ANSI-standard T15 wedge bulbs, with the 912 classified as a variant of the 921. The wattage difference between the two means substituting one for the other may affect light output intensity.
The center high mount stop light on the TITAN transitioned from the 921 bulb in 2004-2008 to the lower-wattage 912 bulb in 2009-2015.
The 3157 is among the most widely used ANSI-standard brake bulbs in North American vehicles, and its dual-filament design allows a single bulb to serve both the running light and brake light functions simultaneously.
