The Dodge 880 front and rear turn signal bulbs both utilize a 1034 size bulb for proper operation. The replacement chart covers vehicle production spanning 1962 to 1965.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge 880 uses the 1034 bulb for both front and rear turn signals across all documented model years, spanning 1962-1965.
The 1034 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
As a dual-filament bulb, the 1034 carries two separate filaments within a single envelope, allowing it to serve more than one lighting function simultaneously, such as turn signaling and running light duties.
The 1034 uses a BAY15d bayonet base, which is an offset twin-pin mount. The asymmetric pin placement of the BAY15d base prevents incorrect insertion, as the two pins sit at different heights.
The 1034 is rated at 12 volts, consistent with the 12-volt electrical systems standard in passenger vehicles of the 1960s.
The 1034 operates at 21/5 watts, where the higher wattage filament corresponds to the brighter turn signal or stop function and the lower wattage filament corresponds to the dimmer running light function.
The 1034 is described as a variant of the 1157 bulb. While the two types share the same BAY15d base and general dual-filament configuration, they are not identical, and substitution between them warrants verification of electrical compatibility before use.
The uniform application of the 1034 across both front and rear positions on the Dodge 880 means a single bulb type covers all four turn signal sockets on the vehicle for every documented model year.
