Additional Notes

The Dodge Aspen map light specifications cover the 1976-1980 model years, with two distinct bulb types appearing across that range: the 562 and the 194.
The 562 festoon bulb is specified for four of the five model years covered, appearing in the 1976 and 1978-1980 Dodge Aspen.
The 562 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal end caps at both tips rather than through a wedge base or pin configuration.
At 44mm in length, the 562 operates at 12 volts and draws 12 watts, placing it among the higher-wattage options typically found in interior lighting applications of that era.
The 1977 Dodge Aspen uses the 194 bulb for the map light, which differs fundamentally in base type from the 562 used in surrounding model years.
The 194 is a miniature wedge bulb of the T10 form factor, securing itself in the socket by friction through a tapered plastic wedge base rather than end caps.
The 194 operates at 12 volts and 3.78 watts, making it significantly lower in wattage than the 562 specified for the other model years.
Because the 562 and 194 use incompatible base types, festoon versus wedge, the two bulbs are not interchangeable despite both being 12-volt ANSI-standard units rated for the US and Canadian markets.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical specifications recognized across North American automotive applications.
The single-year use of the 194 in the 1977 model makes base-type verification particularly relevant when sourcing a replacement for that specific year.
