Additional Notes

The 562 bulb is the most frequently specified map light bulb for the Dodge Omni, covering model years 1978-1983 and 1985, which represents the majority of the vehicle's production span in these records.
The 562 is a festoon-type bulb rated at 12V and 12W, measuring 44mm in length with end-cap contacts. Festoon bulbs seat by pressing lengthwise between two spring clips rather than inserting into a socket.
The 211-2, specified for the 1990 Dodge Omni, is also a festoon bulb but measures 41mm in length with an SV8.5 base, making it physically incompatible with the 562 despite sharing the same voltage and wattage ratings.
The 912, specified for the 1984 model year, is a wedge-type bulb in the T15 form factor rated at 12V and 12W. It is a variant of the 921 bulb and uses a wedge base rather than end-cap contacts, meaning it is not interchangeable with the festoon-type bulbs used in other Omni model years.
The 168, specified for the 1985 model year, is a miniature wedge bulb in the T10 form factor rated at 12V and 4.9W. Its wattage is notably lower than all other bulbs listed in these specifications, which operate at 12W.
All four bulb types listed conform to ANSI standards applicable in both the United States and Canada.
The 1984 and 1985 model years each use a distinct bulb type, meaning no two consecutive years outside of the 1978-1983 range share the same map light bulb specification.
The two festoon bulbs in these specifications, the 562 and the 211-2, differ in length by 3mm and use different base configurations, which prevents cross-year substitution between them.
