Additional Notes

The Chevrolet C-Series Pickup uses the 211-2 bulb for the dome light across all specified model years from 1975 to 2000, with the sole exception of 1987, for which no specification is listed.
The 211-2 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact at both flat ends rather than through a screw or bayonet base.
The bulb carries an SV8.5 base designation, which refers to the flat metal cap contacts at each end of the festoon body, spaced to fit a 41mm housing.
At 12 volts and 12 watts, the 211-2 operates within the standard low-voltage electrical architecture found in automotive interiors.
The 211-2 conforms to ANSI standards recognized in both the United States and Canada, placing it within a regulated specification framework for bulb geometry and electrical ratings.
The 41mm length is a critical fitment factor, as festoon bulbs are retained by spring-loaded clips sized to a specific length; a bulb of a different length will not seat correctly in the dome light housing.
The 211-2 designation is sometimes used interchangeably with the 212-2 in aftermarket listings, though the two types can differ in wattage, and substitution without confirming the wattage rating may affect socket compatibility.
