Additional Notes

The 192 bulb is the sole dome light bulb size listed for the Chrysler 300M across the 1999-2001 model years.
The 192 bulb follows the ANSI standard, which is the recognized specification system for miniature automotive bulbs in the United States and Canada.
It belongs to the T10 form factor, a miniature wedge-base bulb that seats without a separate socket lock, relying instead on tension from the wedge-shaped base to maintain contact.
The 192 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
At 3 watts, the 192 draws relatively low current, which is typical for interior courtesy lighting where prolonged use is common.
The T10 wedge base is a widely produced form factor, meaning the 192 shares physical interchangeability with other T10-based bulbs, though wattage and voltage ratings must match the original specification to avoid electrical or fitment issues.
