The Honda Pilot brake light utilizes a 7443 bulb size for illumination across various production versions. Data for the specified component covers the period from 2003 through 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Pilot uses the 7443 bulb for both the standard brake light and the outer brake light positions across all model years listed, from 2003 to 2015, with no variation between those two positions throughout that span.
The 7443 is a dual-filament T20 wedge bulb rated at 12V with a 21W/5W output, meaning one filament handles the higher-intensity brake function at 21W while the second filament serves a lower-intensity running light function at 5W.
As a wedge-base bulb, the 7443 uses no metal pins or bayonet fittings; instead, the base of the glass envelope itself acts as the electrical contact, which is a common trait across the T20, T15, and T10 wedge families represented in these specifications.
The center high mount stop light on the Honda Pilot uses two different bulb types depending on the model year, with the 921 fitted to 2003-2007 models and the 168 fitted to 2009-2015 models.
The 921 is a single-filament T15 wedge bulb rated at 12V and 16W, while the 168 is a smaller single-filament T10 wedge bulb rated at 12V and 4.9W, making the two bulbs significantly different in both physical size and wattage output.
Because the 921 and 168 differ in both body size and wattage, they are not interchangeable with each other, and substituting one for the other in the center high mount stop light would result in an incorrect fit or improper light output.
All three bulb types listed in these specifications, the 7443, 168, and 921, conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical tolerances across those markets.
The 7443 bulb is not interchangeable with the 7440, a visually similar T20 wedge bulb, because the 7440 is a single-filament variant; installing a 7440 in place of a 7443 would eliminate the secondary filament function.
The shift from the 921 to the 168 in the center high mount stop light between the 2007 and 2009 Honda Pilot corresponds to a generational redesign of the vehicle, which introduced a new lamp assembly requiring the smaller T10 form factor.
No model year within the listed data uses different bulb sizes between the standard brake and outer brake positions, indicating those two circuits share the same 7443 specification across the entire production range covered.
