Additional Notes

The Plymouth Breeze uses the 921 bulb for the back up light across all listed model years, spanning 1996-2000.
The 921 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 921 bulb uses a wedge-style base, designated T15, which refers to a tubular glass envelope roughly 15/8 of an inch wide with a plastic wedge base that seats directly into a socket without a separate metal connector.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
At 16 watts, the 921 falls within the moderate output range for incandescent reverse lighting, reflecting a balance between visibility and power draw.
Because the 921 is an ANSI-standardized type, it is produced by multiple manufacturers, and units from different brands sharing the same designation are generally interchangeable in the Plymouth Breeze back up light socket.
The wedge base design of the T15 eliminates the need for a bayonet or screw-type socket, which means the bulb is retained solely by the tension of the socket contacts against the base.
