Additional Notes

The 562 bulb is the sole map light bulb size listed for the Dodge W100 across all recorded model years in these specifications.
The 562 follows the ANSI standard, meaning it conforms to the American National Standards Institute designation recognized in both the United States and Canada.
It is a festoon-type bulb, a form factor characterized by a cylindrical body with metal end-cap contacts at each end rather than a screw or bayonet base.
The bulb has a total length of 44mm, which is the span between its two end contacts and determines physical fitment within the map light housing.
It operates at 12 volts and draws 12 watts, consistent with standard 12V automotive electrical systems.
The 1988-1989 model years share the 562 specification, as does the 1985 model year, indicating consistent map light hardware across those recorded years.
Because the 562 uses end-cap contacts, substituting a bulb with a different base type, such as a wedge or bayonet, would be physically incompatible with the Dodge W100 map light socket.
When sourcing a replacement, the 44mm festoon length is a critical fitment factor, as festoon bulbs of differing lengths, such as 36mm or 41mm variants, would not seat correctly in the housing.
