Plymouth Satellite Map Light Bulb Size

The Plymouth Satellite map light requires bulb sizes 562, 1895, and 90 depending on the specific application. Data for the lighting components 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 Satellite map light bulb specifications cover the 1965-1974 model years, with three distinct bulb types used across that span: the 562, the 1895, and the 90.
The bulb 90 is the most frequently specified type in these records, appearing across the 1965-1970 model years. It is a single-filament bulb with a BA15s bayonet base, rated at 12V and 13W.
The BA15s bayonet base on the 90 bulb is a single-contact bayonet fitting, which is not interchangeable with dual-contact bayonet bases such as the BA15d. Substitutions using the wrong base type will not seat correctly.
The 562 is specified for the 1972-1974 Plymouth Satellite map light. It is a festoon-style bulb with a 44mm length and end-cap contacts, rated at 12V and 12W.
Festoon bulbs like the 562 make contact at both ends of the bulb body rather than through a base, which means length is a critical fitment factor. A festoon bulb of a different length will not make proper contact in the same housing.
The 1895 is specified exclusively for the 1971 model year. It is a T5 miniature wedge bulb rated at 12V and 0.9W, making it substantially lower in wattage than either the 562 or the 90.
The wattage difference between the 1971 bulb (0.9W) and the surrounding model years is significant. The 90 draws 13W and the 562 draws 12W, meaning these bulb types are not electrically equivalent and are not interchangeable across model years.
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 those markets.
The shift from the 90 bulb to the 1895 in 1971, and then to the 562 in 1972, reflects changes in the map light socket design across those model years, as each bulb type uses a physically distinct mounting and contact method.
Because the 562, 1895, and 90 each use different base or contact configurations, a replacement bulb must match the exact bulb number specified for the given model year to fit the socket correctly.
