Additional Notes

The 212-2 is the map light bulb used across all documented model years of the Chevrolet SSR, covering 2004-2006.
The 212-2 follows the ANSI standard, meaning it conforms to a specification recognized in both the United States and Canada.
This bulb is a festoon type, which is a cylindrical form factor held in place by spring-loaded end caps rather than a socket with a plug-in base.
The 212-2 has a length of 41mm, which is a critical fitment factor, as festoon bulbs must physically span the fixture's contact points to seat correctly.
It uses an SV8.5 base designation, referring to the style and width of the metal end caps that make electrical contact within the festoon holder.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
At 12 watts, the 212-2 draws a moderate amount of power for an interior courtesy-type application.
Because festoon bulbs are sized by both length and base type, substituting a bulb with a different length or a non-SV8.5 base would result in an incompatible fit for the SSR map light housing.
