Additional Notes

The 921 bulb is the sole back up light bulb size listed across all model years of the Ford Edge covered by these specifications, spanning 2007-2015.
The 921 is a wedge-type bulb, classified under the T15 designation, which refers to its tubular glass envelope measuring 15 eighths of an inch in width.
The wedge base design means the 921 requires no separate metal base or locking pins, as the glass envelope itself forms the electrical contact when inserted into the socket.
The 921 operates at 12 volts and 16 watts, which is consistent with standard automotive low-voltage electrical systems.
The 921 conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized specification for the bulb's electrical and physical characteristics.
The 2015 Ford Edge carries a fitment note specifying the 921 bulb applies to vehicles produced up to 12/24/2014, which indicates a mid-production-year change occurred for that model year.
