Additional Notes

The 211-2 and 212-2 are both festoon-type bulbs, meaning they are cylindrical lamps that make contact at each end rather than through a screw or bayonet base.
Both bulb types share the SV8.5 base designation, which refers to a festoon base with an 8.5mm cap width.
The GMC Yukon used the 211-2 bulb for its dome light across the 1992-1999 model years.
The 2014 GMC Yukon uses the 212-2 bulb for its dome light, which differs from the 211-2 used in earlier model years.
Despite the difference in part numbers, both the 211-2 and 212-2 share identical electrical ratings of 12 volts and 12 watts, as well as the same 41mm length and SV8.5 base.
Because the 211-2 and 212-2 share the same physical and electrical specifications, they are widely regarded in the industry as interchangeable in many applications.
Both bulb types conform to ANSI standards recognized in the United States and Canada, indicating they meet a defined set of performance and construction criteria.
