Additional Notes

The Cadillac XLR uses the 212-2 bulb for the map light across all model years from 2004 to 2009.
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-type bulb, which is a cylindrical lamp 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 a common festoon size found in many interior lighting applications across various vehicle makes.
It uses an SV8.5 base, a designation that refers to the end-cap style specific to festoon bulbs, with the "8.5" indicating the cap width in millimeters.
The 212-2 operates at 12 volts, consistent with the standard electrical system voltage of most passenger vehicles.
The bulb carries a 12-watt rating, which reflects its power consumption and influences the brightness output in the map light position.
When replacing the map light bulb in the Cadillac XLR, fitment requires matching both the 41mm festoon length and the SV8.5 base to ensure proper physical installation and electrical contact.
