Ford Consul front and rear turn signal bulbs utilize 1034 and 1154 bulb sizes across the vehicle's lighting system. 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 Consul uses two bulb types across its turn signal positions: the 1154 for model years 1951-1955 and the 1034 for model years 1956-1957, applying equally to both front and rear turn signal positions in each respective period.
Both the 1034 and 1154 are ANSI-standardized bulbs recognized in the United States and Canada, and both share the BAY15d bayonet base, a double-contact base with two offset pins that prevent incorrect installation orientation.
Both bulb types carry dual-filament construction, meaning each bulb contains two separate filaments that serve different lighting functions within a single housing.
The 1034 and 1154 are each described as variants of the 1157, a widely used automotive bulb, with the 1154 representing an older variant and the 1034 a closer derivative of that same standard.
The 1034 operates at 12V with a 21/5W output, where the two wattage values correspond to its two filaments, typically associated with turn signal and parking light functions respectively.
The 1154 is rated for either 6V or 12V operation, reflecting its design for older electrical systems where 6-volt configurations were common before the automotive industry standardized on 12-volt systems.
Despite sharing the same BAY15d base type, the 1034 and 1154 are not confirmed as interchangeable in the Ford Consul specifications, and the voltage difference between the two types is a relevant factor in that distinction.
