Dodge Seneca front and rear turn signal bulbs both utilize the 1034 size. The replacement chart covers 1960 to 1961 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1034 bulb is the sole bulb type specified for the Dodge Seneca across all listed turn signal positions and model years.
The 1034 is an ANSI-standard bulb recognized in both the United States and Canada, operating at 12 volts with a dual-filament design rated at 21/5 watts.
A dual-filament bulb contains two separate filaments within a single envelope, allowing it to serve two distinct functions, such as turn signaling and running light operation, from one unit.
The 1034 uses a BAY15d bayonet base, a two-pin offset base type that physically prevents incorrect insertion by positioning its two pins at different heights.
The 1034 is a variant of the 1157 bulb. While the two share the same BAY15d base and general dual-filament configuration, they are not identical, and substitution between them may affect electrical compatibility or light output.
The 1034 bulb applies to both the front and rear turn signal positions on the Dodge Seneca for the 1960-1961 model years.
