Dodge Polara License Plate Bulb Size

Additional Notes

• The bulb 67 is the most frequently specified license plate bulb for the Dodge Polara, covering model years 1960-1972 without interruption across ten consecutive years from 1960-1969, and continuing through 1972 with two exceptions.
• The bulb 67 follows the ANSI standard for the US and Canada, operates at 12V and 8W, and uses a BA15s single-contact bayonet base, classifying it as a lower wattage variant of the widely known 1156 bulb type.
• The BA15s bayonet base is a single-contact fitting, meaning only one electrical contact is present at the base, which distinguishes it from dual-contact bayonet types used in dual-filament applications.
• The bulb 97 shares the same BA15s bayonet base as the 67 but draws 13W rather than 8W, making the two physically interchangeable in terms of base type while differing in power consumption.
• Because the 97 and 67 share the BA15s base, substituting one for the other in the Dodge Polara (1971-1972) is a fitment consideration, as the wattage difference may affect circuit load and illumination output.
• The 1973 Dodge Polara uses the 168, a T10 miniature wedge bulb, which represents a fundamentally different base type from the BA15s bayonet used in all prior model years, making earlier bulb types physically incompatible with the 1973 socket.
• The 168 wedge bulb operates at 12V and 4.9W, the lowest wattage of the three bulb types listed across the Polara's license plate specifications.
• The T10 wedge format of the 168 relies on the bulb's glass envelope and wire leads to make electrical contact directly with the socket, requiring no separate base pin or bayonet fitting.
