Dodge Power Wagon front and rear turn signal bulbs utilize 1034 and 1129 size specifications. The replacement chart covers 1950 through 1957 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 Dodge Power Wagon uses two bulb types across its turn signal specifications: the 1034 and the 1129, both of which are ANSI-standardized bulbs recognized in the US and Canada.
Both the 1034 and 1129 are dual-filament bulbs, meaning each contains two separate filaments within a single envelope, allowing one bulb to serve more than one lighting function simultaneously.
Both bulb types share the BAY15d bayonet base, a two-pin offset base design that physically locks the bulb into its socket with a twist-and-seat motion.
The 1034 and 1129 are each classified as variants of the 1157, a widely used automotive bulb standard, indicating close functional and physical relationships among the three types.
Both bulbs operate at 12 volts with a 21/5-watt dual-filament output, where the higher wattage filament serves the turn signal function and the lower wattage filament serves a secondary purpose such as running or parking light duty.
The Dodge Power Wagon (1956-1957) uses the 1034 bulb in both the front and rear turn signal positions, with the same bulb type applied uniformly across both locations in those model years.
The 1129 bulb is specified for the Dodge Power Wagon across model years 1950-1955, again applied uniformly to both the front and rear turn signal positions in each of those years.
Although the 1034 and 1129 share the same base type, voltage, and wattage ratings as each other and are both variants of the 1157, they carry distinct ANSI designations and are not confirmed as interchangeable within these specifications.
