The Dodge Wayfarer front and rear turn signal bulbs utilize 1154 and 1158 bulb sizes for this vehicle model. The replacement chart covers 1950 to 1952 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1154 bulb is an ANSI-standardized dual-filament type with a BAY15d bayonet base, rated for use on both 6V and 12V electrical systems, and is noted as an older variant of the more widely recognized 1157 bulb.
The 1158 bulb shares the same ANSI-standardized dual-filament construction and BAY15d bayonet base as the 1154 but is rated exclusively for 12V systems.
A BAY15d bayonet base features two offset pins at different heights, a design that prevents incorrect bulb insertion by ensuring only one rotational orientation is possible.
The Dodge Wayfarer (1951-1952) uses the 1154 bulb for both front and rear turn signals, meaning the same bulb type serves all four turn signal positions in those model years.
The 1950 Dodge Wayfarer uses the 1158 bulb for both front and rear turn signals, distinguishing it from the 1951-1952 fitment.
Although the 1154 and 1158 share the same BAY15d base, they are not the same bulb. The 1154 supports dual-voltage operation while the 1158 is limited to 12V, which is a relevant distinction for vehicles with non-standard electrical systems.
The shift from the 1158 in 1950 to the 1154 in 1951-1952 represents a change in bulb specification across the Wayfarer's production run, affecting all turn signal positions simultaneously.
