Ford Galaxie 500 front turn signal bulbs utilize 1157NA, 1034NA, or 1157 bulb sizes, while rear turn signal bulbs use 1157 or 1034 sizes. The replacement chart covers 1962 through 1974 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 Galaxie 500 turn signal specifications cover model years 1962-1974, spanning both front and rear positions across the full production run represented in the data.
All four bulb types listed across these specifications, the 1157NA, 1034NA, 1157, and 1034, share the BAY15d bayonet base and operate at 12V with a dual-filament configuration rated at 21W and 5W respectively.
The 1157 is the most consistently used bulb type in the Galaxie 500 specifications, serving as the rear turn signal fitment for every model year from 1963-1974.
The "NA" suffix on the 1157NA and 1034NA designates natural amber glass, meaning the amber color is built into the bulb itself rather than produced by a colored lens or housing.
The 1034 and 1034NA are described as variants of the 1157 family, sharing the same BAY15d base and 12V/21W/5W ratings, though they carry distinct ANSI designations.
The Ford Galaxie 500 front and rear turn signals do not always share the same bulb type for a given model year, as the front position uses NA-suffix amber bulbs in most years while the rear position uses the clear-glass 1157 throughout 1963-1974.
The 1962 Galaxie 500 is the only model year in these specifications where both the front and rear turn signal positions use the same bulb, the 1034, in its non-amber variant.
The front turn signal on the 1969 and 1963 Galaxie 500 uses the standard 1157 rather than the 1157NA, making those two years distinct from the majority of other front-position fitments in the specification set.
Because the 1034NA and 1157NA share the BAY15d base with the 1157 and 1034, physical socket compatibility exists across the family, though substituting a non-NA bulb for an NA-designated position would affect the amber output if the housing lens is clear.
The front turn signal shifted from the 1034NA (1970-1971) back to the 1157NA (1972-1974), indicating that the two variant types were used interchangeably across different production periods on the Galaxie 500.
