Additional Notes

The 912 bulb is the cargo box bulb size for the Subaru Forester across the 2021-2023 model years.
The 912 is an ANSI-standardized bulb type, meaning it conforms to a defined set of electrical and physical specifications recognized in the United States and Canada.
It uses a wedge-style base in a T15 envelope, which refers to the tubular glass shape measuring 15 eighths of an inch in width.
The 912 operates at 12 volts and draws 12 watts, placing it in the lower output range typical of interior and cargo lighting applications.
The 912 is a variant of the 921 bulb. While the two share the same T15 wedge form factor and 12-volt rating, the 921 is rated at 18 watts, making the two types electrically non-equivalent despite their physical similarities.
