Additional Notes

The Honda HR-V uses the 921 bulb size for its back up light across the 2016-2023 model years.
The 921 bulb follows the ANSI standard, which is the recognized specification framework used in the United States and Canada for automotive lighting components.
This bulb belongs to the T15 form factor, a wedge-type base design that connects by pressing directly into a socket without a separate metal base or pins.
The 921 operates at 12 volts, which is consistent with standard 12V automotive electrical systems found in passenger vehicles.
The bulb carries a 16-watt power rating, placing it in the range typical for reverse lighting applications where moderate output is required.
Because the 921 is an ANSI-standardized bulb, it is produced by multiple manufacturers to the same electrical and physical specifications, meaning units from different brands are generally interchangeable within that standard.
The wedge base construction of the T15 means fitment depends on socket compatibility with that specific base type, and substituting a bulb with a different base style would not be physically compatible regardless of voltage or wattage.
