Additional Notes

The Honda Pilot tail light uses the 7443 bulb across all listed model years from 2003-2015.
The 7443 is a T20 wedge-base bulb, meaning it uses a plastic wedge-shaped base rather than a metal bayonet or screw fitting for retention in the socket.
The 7443 operates at 12 volts, which is standard for automotive electrical systems.
As a dual-filament bulb, the 7443 houses two separate filaments within a single globe, rated at 21W and 5W respectively, allowing it to serve two lighting functions from one unit.
The higher 21W filament typically handles the brighter stop or turn signal function, while the lower 5W filament handles the dimmer running or parking light function.
The 7443 conforms to ANSI standards as recognized in both the United States and Canada.
The T20 designation refers to the bulb's globe size, where the number 20 represents a width of 20 eighths of an inch, a sizing convention common across ANSI-coded automotive bulbs.
Because the 7443 is a dual-filament type, substituting it with a single-filament alternative such as the 7440 would result in the loss of one lighting function at that socket position.
