Plymouth Fury III Map Light Bulb Size

The Plymouth Fury III map light requires bulb sizes 90, 1895, and 562 depending on the specific vehicle configuration. Data for the map light covers the range from 1965 to 1974.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Plymouth Fury III map light specifications cover model years 1965 through 1974, with three distinct bulb types appearing across that span: the 562, the 1895, and the 90.
The bulb 90 is the most frequently specified type in these records, covering the Plymouth Fury III from 1965 through 1970. It is a single-filament bulb with a BA15s bayonet base, rated at 12V and 13W.
The BA15s bayonet base on the 90 bulb uses a single contact pin, which is not interchangeable with BA15d double-contact bayonet bases found on other automotive bulbs.
The 562 festoon bulb is specified for the 1972 and 1974 Plymouth Fury III. It measures 44mm in length and makes contact through end caps rather than a base pin or wedge, operating at 12V and 12W.
Festoon bulbs rely on spring-loaded holders that grip both end caps, so the 44mm length of the 562 is a critical fitment factor. A festoon bulb of a different length will not seat correctly in a holder sized for the 562.
The 1971 Plymouth Fury III is the only model year in these specifications to use the 1895 bulb. It is a T5 miniature wedge type, rated at 12V and 0.9W, making it substantially lower in wattage than the other two bulb types listed.
The wedge base of the 1895 bulb is held in place by friction within its socket and has no pins or end caps, which means it is physically incompatible with the bayonet socket used by the 90 or the festoon holder used by the 562.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical ratings across all listed model years.
The 562 and the 90 have relatively close wattage ratings of 12W and 13W respectively, but their base types differ entirely, as one uses end-cap festoon contacts and the other uses a bayonet mount, making them non-interchangeable despite similar power draw.
The shift from the 90 bulb in 1970 to the 1895 in 1971 and then to the 562 in 1972 reflects changes in socket design across those production years, and substituting a bulb from a different year's specification would require a compatible socket type.
