The Honda Crosstour brake light requires a bulb size of 7443 for the specific lighting components located at the rear of the vehicle. Data for the bulb specifications covers the range from 2012 to 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Crosstour uses the 7443 bulb for brake lighting across all documented model years, spanning 2012-2015.
The 7443 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
This bulb follows the T20 wedge form factor, a designation that refers to its physical base style and approximate size classification within the wedge bulb family.
The 7443 operates at 12 volts, which is consistent with standard automotive electrical systems.
As a dual-filament bulb, the 7443 carries two separate filaments rated at 21W and 5W, allowing it to serve both a high-intensity brake function and a lower-intensity running light function within a single housing.
The same 7443 bulb specification applies to both the general brake position and the outer brake position on the Honda Crosstour, indicating a shared bulb type across those two distinct lamp locations.
Because the 7443 is a dual-filament bulb, substituting it with a single-filament equivalent such as the 7440 would result in the loss of one lighting function, making direct replacement with the correct dual-filament type necessary for proper operation.
