Additional Notes

The 912 is the sole bulb type listed for the Chrysler Executive Sedan map light across both documented model years, 1983-1984.
The 912 bulb follows the ANSI standard, meaning it conforms to a specification recognized across the United States and Canada.
It uses a wedge base construction, which relies on the bulb's glass envelope being held directly by spring contacts rather than a separate metal base with pins.
The T15 designation refers to the tubular bulb shape, with the numeric portion indicating a width of 15 eighths of an inch.
The 912 operates at 12 volts and 12 watts, consistent with standard automotive electrical systems.
The 912 is documented as a variant of the 921 bulb. These two types share the same wedge base and voltage rating, though the 921 operates at a higher wattage of 16.8 watts, making them physically interchangeable in many sockets but electrically distinct.
