Additional Notes

The Plymouth TC3 uses the 562 bulb for the map light across the 1980-1982 model years.
The 562 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
The 562 is a festoon-style bulb, which is a cylindrical lamp that makes contact at both ends rather than through a base socket, allowing it to seat horizontally between two spring clips.
The 562 bulb has a 44mm length, which is the span between its two end-cap contacts and determines physical fitment within the festoon holder.
It operates at 12 volts and 12 watts, values consistent with standard automotive electrical systems of that era.
Because festoon bulbs are sized by their contact-to-contact length, substituting a festoon bulb of a different length, even one with the same voltage and wattage, would result in an improper fit in the Plymouth TC3 map light housing.
