Chrysler E Class Map Light Bulb Size

The Chrysler E Class map light requires bulb size 562 or 912 depending on the specific configuration of the interior lighting system. Data for the bulb sizes covers the range from 1983 to 1984.

Additional Notes

The Chrysler E Class map light uses two different bulb types across its model years: the 562 for the 1984 model year and the 912 for the 1983 model year.
The 562 is a festoon-style bulb with a 44mm length and end-cap contacts, operating at 12V and 12W. Festoon bulbs seat by pressing their end caps into spring clips rather than inserting into a socket.
The 912 is a wedge-style bulb in the T15 form factor, also rated at 12V and 12W. Wedge bulbs use the wire filament leads bent around the base to make electrical contact, requiring no separate socket pins.
Both the 562 and 912 carry ANSI standardization for the US and Canadian markets, meaning their physical and electrical specifications conform to a defined industry standard rather than a proprietary format.
Although the 562 and 912 share identical voltage and wattage ratings, their base types are physically incompatible. The festoon end-cap design of the 562 cannot be substituted into a wedge socket intended for the 912, and vice versa.
The 912 is noted as a variant of the 921 bulb. While the two share the same T15 wedge form factor and voltage, the 921 typically carries a higher wattage rating of 18W, making the bulbs non-interchangeable despite their physical similarity.
