Additional Notes

The Chevrolet Blazer uses the 211-2 bulb for trunk lighting across the 1995-2003 model years.
The 211-2 is a festoon-type bulb, meaning it mounts by pressing horizontally between two spring clips rather than inserting into a socket.
The 211-2 operates at 12 volts and draws 12 watts, which is typical for interior cargo illumination applications.
The bulb measures 41mm in length and uses an SV8.5 base, which defines the contact cap style at each end of the festoon body.
The 211-2 designation follows ANSI standards recognized in both the United States and Canada, indicating a standardized specification rather than a proprietary part number.
The SV8.5 base designation refers to a single-contact festoon cap with an 8.5mm cap width, a detail relevant when substituting with alternative festoon bulbs of the same length.
Festoon bulbs of the same 41mm length but with a different base type, such as the SV7 or SV10, are not interchangeable with the 211-2 despite sharing the same physical length.
