Additional Notes

The Chevrolet G-Van uses the 211-2 bulb size for the dome light across the 1975-1995 model years.
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 211-2 bulb operates at 12 volts and draws 12 watts, which is typical for interior dome lighting in full-size vans of this era.
The 211-2 follows the ANSI standard, indicating it meets a defined specification recognized in both the United States and Canada.
The bulb uses an SV8.5 base designation, which refers to the festoon cap size and is a standard identifier used to confirm physical fitment compatibility.
The 211-2 has a 41mm length, which is the critical fitment factor for festoon bulbs, as the spring clips in the housing are spaced to a fixed distance.
Festoon bulbs of different lengths, such as the common 31mm or 36mm variants, are not interchangeable with the 211-2 even if they share a similar appearance, as the length mismatch would prevent proper contact with the mounting clips.
