Additional Notes

The Cadillac Escalade EXT uses two bulb types across its model years for the dome light: the 211-2 for 2002-2006 and the 212-2 for 2007-2013.
Both the 211-2 and 212-2 are festoon-style bulbs, meaning they are cylindrical and held in place by spring clips at each end rather than a screw or bayonet base.
Each bulb carries an SV8.5 base designation, which refers to the end-cap style used on festoon bulbs with a nominal 8.5mm cap width.
Both bulbs share a 41mm length, a 12-volt operating voltage, and a 12-watt power rating, making their electrical and physical profiles identical.
Despite their near-identical specifications, the 211-2 and 212-2 are distinct ANSI-designated part numbers, and fitment should follow the year-specific listing rather than treating them as freely interchangeable.
Both designations conform to ANSI standards recognized in the United States and Canada, indicating standardized performance and dimensional tolerances across manufacturers.
At 12 watts, these bulbs fall within the typical incandescent output range for interior dome lighting in full-size trucks and SUVs of that era.
