Additional Notes

The 211-2 is the sole dome light bulb type listed for the Dodge Royal Monaco across the 1975-1977 model years.
The 211-2 is an ANSI-standardized bulb, meaning it conforms to a defined North American specification recognized in both the United States and Canada.
The 211-2 is a festoon-type bulb, which is a cylindrical lamp that mounts by pressing its two end caps into spring clips rather than using a threaded or bayonet socket.
The bulb measures 41mm in length, which is the end-to-end span of the festoon body and determines physical fit within the dome light housing.
The 211-2 uses an SV8.5 base, a designation that refers to the 8.5mm width of the metal end caps on a festoon bulb.
The bulb operates at 12 volts, consistent with the standard electrical system voltage of passenger vehicles of that era.
The 211-2 carries a 12-watt rating, which reflects its power draw and influences the brightness output within the dome fixture.
Because festoon bulbs are sized by both length and base width, substituting a festoon bulb of a different length or base width than 41mm and SV8.5 would result in an incompatible fit for the Royal Monaco dome light housing.
