Additional Notes

The Honda CR-V uses the 921 bulb for the cornering position across the 2021-2023 model years.
The 921 is an ANSI-standard bulb, meaning it follows the North American specification system used in the United States and Canada.
It is a T15 wedge-type bulb, which uses a plastic wedge base inserted directly into a socket rather than a separate metal base.
The 921 operates at 12V and draws 16W of power.
The 2005-2006 Honda CR-V uses the P21W bulb for the cornering position instead.
The P21W follows the ECE standard, which is the regulatory framework applied in Europe and many other markets worldwide, making it a different specification family from the ANSI-based 921.
The P21W uses a BA15s bayonet base, a single-contact fitting that locks into its socket with a quarter-turn motion.
At 12V and 21W, the P21W draws notably more power than the 921, which means the two bulbs are not interchangeable despite sharing the same 12V operating voltage.
The difference in base type between the two bulbs, wedge for the 921 and bayonet for the P21W, also makes physical substitution between them impossible without modification.
Both bulbs are single-filament designs, a characteristic consistent with their use in a dedicated cornering function rather than a dual-purpose lighting role.
