Additional Notes

The Dodge Aries map light draws from three distinct bulb types across its production years: the 168, 912, and 211-2.
The 912 is the most frequently specified bulb in the Dodge Aries map light fitment, covering the 1982-1987 model years.
The 912 is a T15 wedge bulb rated at 12V and 12W, and it is classified as a variant of the 921 under the ANSI standard used in both the US and Canada.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, also conforming to the ANSI standard for the US and Canadian markets. It applies to the 1988-1989 Dodge Aries.
The 211-2 is a festoon-style bulb with an SV8.5 base and a 41mm length, rated at 12V and 12W under the same ANSI standard. It is specified for the 1981 Dodge Aries.
The T10 and T15 designations refer to the bulb's tubular envelope width, measured in eighths of an inch, making the T15 physically larger than the T10.
The wattage difference between the 168 (4.9W) and the 912 (12W) is significant. Substituting one for the other without accounting for this difference risks improper illumination or electrical load mismatches.
The festoon format of the 211-2 is mechanically distinct from the wedge format of both the 168 and 912, meaning these types are not interchangeable regardless of voltage or wattage ratings.
The transition from the 211-2 in 1981 to the 912 in 1982 represents a shift from a festoon-mount to a wedge-mount socket, indicating a likely change in the map light housing design between those model years.
The transition from the 912 to the 168 between the 1987 and 1988 model years reflects a change to a lower-wattage T10 wedge bulb, which draws notably less power than the T15 it replaced.
