Ford Victoria front and rear turn signal bulbs utilize 1034 and 1154 sizes. The replacement chart covers 1951 through 1957 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 Ford Victoria uses two bulb types across its turn signal positions: the 1034 for 1956-1957 models and the 1154 for 1951-1955 models, applying equally to both front and rear positions in each respective year range.
Both the 1034 and 1154 are ANSI-standardized bulbs recognized in the United States and Canada, and both share the BAY15d bayonet base, a two-pin offset base design that locks the bulb into its socket with a twist.
Both bulb types carry dual-filament construction, meaning each bulb serves two lighting functions within a single housing, typically combining a brighter filament for turn signaling with a dimmer filament for running or parking light duty.
The 1034 bulb operates at 12V with a rated output of 21/5W, where the higher wattage corresponds to the turn signal filament and the lower wattage to the secondary filament.
The 1154 bulb is rated for both 6V and 12V operation, reflecting its origin in an era when automotive electrical systems were transitioning between those two voltages.
Both the 1034 and 1154 are described as variants of the 1157 bulb, a widely produced BAY15d dual-filament type, though they are not direct replacements for one another due to differences in voltage rating and wattage.
The Ford Victoria (1956-1957) uses the 1034 bulb across all four turn signal positions, with no distinction between front and rear fitment in those model years.
The shared BAY15d base between the 1034 and 1154 means the two bulbs are physically interchangeable in terms of socket fit, but their differing voltage and wattage specifications make substitution between them a technical concern rather than a straightforward swap.
