Additional Notes

The Dodge St. Regis map light uses two distinct bulb types across its model years: the 562 and the 214-2, both classified as festoon bulbs under ANSI standards recognized in the US and Canada.
Festoon bulbs are cylindrical lamps that make electrical contact at both ends of the housing rather than through a side or screw base, which is a common format for interior map and dome lighting applications.
The 562 bulb is specified for the 1979 and 1981 Dodge St. Regis, operating at 12 volts and 12 watts with end-cap contacts and a 44mm length.
The 214-2 bulb is specified for the 1980 model year, also rated at 12 volts and 12 watts, but with a 41mm length and an SV8.5 base rather than plain end-cap contacts.
Although the 562 and 214-2 share identical voltage and wattage ratings, their physical lengths differ by 3mm, and their contact configurations are not the same, making them non-interchangeable despite the electrical similarity.
The SV8.5 base designation on the 214-2 refers to a festoon base with a specific cap width of 8.5mm, a detail that affects physical fitment within the lamp socket.
The shift from the 562 in 1979 to the 214-2 in 1980 and back to the 562 in 1981 indicates that the correct bulb type is year-specific and should not be assumed consistent across the St. Regis production run.
