Additional Notes

The 168 bulb is an ANSI-standard miniature wedge type with a T10 form factor, rated at 12V and 4.9W, recognized across both the US and Canada.
The 912 bulb is an ANSI-standard wedge type with a T15 form factor, rated at 12V and 12W, and is classified as a variant of the 921 bulb.
The Plymouth Turismo 2.2 uses a 168 bulb for the map light in the 1985 model year and a 912 bulb in the 1984 model year, meaning the two model years are not interchangeable in this application.
The wattage difference between the two bulbs is notable: the 912 draws 12W compared to the 4.9W of the 168, reflecting a significant difference in power consumption for the same map light position across the two model years.
The T10 and T15 designations refer to the outer width of the wedge base, with T15 being physically larger than T10, which is a factor in socket fitment between the 1984 and 1985 Turismo 2.2.
