Additional Notes

The Ford Ranger (2021-2023) uses a 912 bulb for the cargo box light.
The 912 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It follows a T15 wedge base design, which means the base of the bulb itself acts as the connector, with no separate metal pins or screw fittings.
The 912 operates at 12 volts and draws 12 watts, which is consistent with standard automotive low-power auxiliary lighting.
The 912 is a variant of the 921 bulb. While the two share the same T15 wedge form factor, they are not identical, and substituting one for the other may produce differences in output or fitment depending on the socket.
