Additional Notes

The 7440 is the tail light bulb size for the Volkswagen Atlas across the 2018 and 2020 model years.
The 7440 follows the ANSI standard, making it a regulated specification used across the United States and Canada.
This bulb uses a T20 wedge base, which is a single-contact, single-filament design that seats without a separate socket lock.
Operating at 12 volts and 21 watts, the 7440 is rated for standard automotive electrical systems.
The single-filament construction of the 7440 means it serves one lighting function per bulb, as opposed to dual-filament types that combine two functions such as stop and tail in one unit.
