Additional Notes

The 211-2 is an ANSI-standardized bulb used in the United States and Canada, operating at 12 volts and 12 watts.
The 211-2 follows a festoon form factor, meaning it is a cylindrical bulb that mounts by pressing between two spring clips rather than inserting into a socket.
The bulb measures 41mm in length and uses an SV8.5 base, which refers to the cap size at each end of the festoon body.
The Chevrolet Classic uses the 211-2 bulb for the trunk across the 2004-2005 model years.
Festoon bulbs of differing lengths are not interchangeable even when voltage and wattage ratings match, as the physical length must correspond to the spacing of the mounting clips in the housing.
