Chrysler Nassau front and rear turn signal bulbs utilize 1034 and 1129 size specifications. The replacement chart covers 1955 to 1956 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler Nassau uses two distinct bulb types across its model years: the 1034 for 1956 and the 1129 for 1955, both in the front and rear turn signal positions.
Both the 1034 and 1129 are ANSI-standardized bulbs recognized in the United States and Canada.
Each bulb carries a dual-filament design, which allows a single bulb to serve two separate lighting functions, typically a brighter filament for the turn signal and a dimmer one for a running or parking light.
Both bulbs use a BAY15d bayonet base, a two-pin offset base type where the two pins are positioned at different heights to ensure correct orientation during installation.
The 1034 and 1129 are each classified as variants of the 1157 bulb, meaning they share the same base type and general configuration but differ in specific electrical characteristics from the 1157 standard.
Both bulbs operate at 12 volts with a 21/5 watt output, where the higher wattage corresponds to the turn signal filament and the lower wattage to the secondary filament.
Although the 1034 and 1129 share the same voltage rating, wattage rating, base type, and 1157 variant classification, they carry different ANSI part numbers, which indicates they are not confirmed as interchangeable between the 1955 and 1956 model years.
The front and rear turn signal positions on the Chrysler Nassau use identical bulb specifications within each model year, with the 1034 appearing in both positions for 1956 and the 1129 in both positions for 1955.
