Additional Notes

The Dodge Spirit map light draws from three distinct bulb types across its 1989-1995 model years: the 168, 906, and 912.
The 168 bulb is a miniature wedge type in the T10 form factor, rated at 12V and 4.9W under the ANSI standard recognized in both the US and Canada.
The 906 shares the same T10 miniature wedge form factor as the 168 but operates at a higher wattage of 8W, also at 12V and under the same ANSI standard.
The 912 is a T15 wedge bulb rated at 12V and 12W, making it physically larger and more powerful than either the 906 or the 168.
The 912 is documented as a variant of the 921 bulb, which indicates a close relationship in physical and electrical design between the two, though they are not identical.
The Dodge Spirit (1989-1992) uses the 168 bulb for the map light across four consecutive model years, representing the longest single-bulb run in the Spirit's map light history.
The 1993 Dodge Spirit transitions to the 906 bulb, which shares the T10 form factor with the 168 but draws nearly twice the wattage, meaning the two are not electrically interchangeable despite their physical similarities.
The 1994-1995 model years specify the 912, a T15 bulb, which is physically distinct from the T10 bulbs used in all prior Spirit model years and is not interchangeable with them.
