Additional Notes

The Jeep J-2700 used the 212-2 bulb for its dome light across the 1965-1968 model years.
The 212-2 is an ANSI-standardized bulb, meaning it conforms to a defined set of electrical and physical specifications recognized across the United States and Canada.
The 212-2 is a festoon-type bulb, which is a cylindrical lamp that mounts by pressing its two end caps into spring clips rather than threading or plugging into a socket.
The 212-2 has an SV8.5 base, a designation that refers to the 8.5mm cap width on a single-contact festoon fitting.
The bulb operates at 12 volts and draws 12 watts, consistent with standard 12-volt automotive electrical systems of that era.
The 212-2 has a 41mm length, which is a critical fitment factor, as festoon bulbs must match the physical span of the mounting clips to seat correctly.
Because festoon bulbs are sized by both length and base type, substituting a bulb of a different length or base width would result in an improper fit even if the voltage and wattage ratings matched.
