Chrysler Newport License Plate Bulb Size

The Chrysler Newport license plate light uses bulb sizes 168, 97, 67, and 63 depending on the specific production period for the vehicle. Available data for the lighting components spans the period from 1950 to 1981.

Additional Notes

The Chrysler Newport license plate bulb specifications span 1950 to 1981, with three distinct bulb types used across that period before settling on a fourth type in the later years.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W under the ANSI standard. Its wedge base design requires no metal base shell, as the glass envelope itself acts as the retaining element in the socket.
The Chrysler Newport (1974-1981) uses the 168 bulb for the license plate position, making it the most recent and longest-running single bulb type in these specifications at eight consecutive model years.
The 67 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 8W. It is a lower-wattage variant of the 1156 bulb, sharing the same base configuration but drawing less power.
The Newport used the 67 bulb across 1956-1970, the widest span of any bulb type in these specifications at fifteen model years.
The 97 bulb also carries a BA15s bayonet base and is rated at 12V and 13W, making it a higher-wattage variant of the 1156 than the 67. Despite sharing the same base type as the 67, the wattage difference means the two are not interchangeable without consideration of the circuit's design tolerance.
The Newport used the 97 bulb for the license plate position during 1971-1973, positioned between the 67 and 168 eras in the model's history.
The 63 bulb uses a BA9s base, which is physically smaller than the BA15s base found on the 67 and 97 bulbs. This base incompatibility means the 63 cannot be substituted into sockets designed for either of those types.
At 0.63W, the 63 bulb draws considerably less power than any other bulb type in these specifications. The Newport used it from 1950 to 1955.
Three of the four bulb types in these specifications, the 97, 67, and 1156, share the BA15s bayonet base, but their differing wattage ratings reflect distinct electrical characteristics that affect direct substitution.
