Additional Notes

The Freightliner Cascadia rear reading light uses the 211-2 bulb across all listed model years, spanning 2008-2017.
The 211-2 is a festoon-type bulb, meaning it is cylindrical in shape and 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 8.5mm width of the contact caps at each end of the festoon body.
The 211-2 operates at 12 volts and draws 12 watts, placing it in the range typical for interior cabin lighting applications.
The 211-2 carries ANSI standardization, meaning the specification is recognized across both the United States and Canada, and the bulb is produced by multiple manufacturers to the same standard.
Because the 211-2 is an ANSI-standardized festoon type, substitutes must match the 41mm length and SV8.5 base to seat correctly in the factory fixture. Festoon bulbs of different lengths will not make proper contact with the spring clips.
