Additional Notes

The Honda Crosstour uses the 7443 bulb for its tail lights across the 2012-2015 model years.
The 7443 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard used in the United States and Canada.
The 7443 belongs to the T20 wedge bulb family, which refers to its wedge-shaped base that allows it to be inserted directly into a socket without a separate metal base or pins.
As a dual-filament bulb, the 7443 contains two separate filaments within a single glass envelope, allowing it to serve two distinct lighting functions from one unit.
The 7443 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
The two filaments in the 7443 are rated at 21 watts and 5 watts respectively, where the higher-wattage filament typically handles braking illumination and the lower-wattage filament handles running light duty.
Because the 7443 is a dual-filament type, substituting it with a single-filament bulb of similar size would result in the loss of one lighting function, making direct replacement with the correct type necessary for proper operation.
