Additional Notes

The Buick Enclave dome light uses the 212-2 bulb across all listed model years, spanning 2008-2018.
The 212-2 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 212-2 is a festoon-style bulb, a cylindrical form factor that mounts by pressing its two end caps into spring clips rather than inserting into a socket.
The bulb has a length of 41mm, which is the critical fitment factor for festoon bulbs, as the housing clip spacing must match this figure.
It uses an SV8.5 base, a designation that refers to the end-cap style and width of the festoon bulb, with 8.5 indicating the cap width in millimeters.
The 212-2 operates at 12 volts, consistent with standard automotive electrical systems.
The bulb carries a 12-watt rating, which reflects its power draw from the vehicle's electrical system during operation.
Because the 212-2 is an ANSI-standardized part, aftermarket and OEM replacements from different manufacturers sharing this designation are expected to conform to the same electrical and physical specifications.
Festoon bulbs of differing lengths are not interchangeable with the 212-2, even if they share the SV8.5 base designation, as an incorrect length will not seat properly in the spring clips.
