Ford Torino front turn signal bulbs utilize 1034NA or 1157NA size specifications, while rear turn signal bulbs require 1157 size. The replacement chart covers 1968 through 1976 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Torino front turn signal position uses two bulb types across the 1968-1976 model years: the 1034NA and the 1157NA, which alternate depending on the specific year.
The rear turn signal position on the Ford Torino uses the 1157 bulb across all model years covered in the specifications, from 1968 through 1976.
All three bulb types listed in these specifications share the BAY15d bayonet base, a double-contact base with two offset pins that prevent incorrect installation orientation.
All three bulbs are dual-filament types, meaning each bulb serves two functions within a single housing, typically combining turn signal and parking or running light duties.
The 1034NA and 1157NA are both rated at 12V with a 21W/5W power draw, where the higher wattage filament handles the turn signal function and the lower wattage filament handles the running light function.
The 1034NA is described as a variant of the 1157, sharing the same BAY15d base and wattage ratings, though it features natural amber glass rather than a clear envelope.
The 1157NA similarly carries natural amber glass, which produces an amber output without relying on an amber-tinted lens, distinguishing it from the clear-envelope 1157 used at the rear.
Because the 1034NA and 1157NA share the BAY15d base with the standard 1157, physical fitment across these three types is mechanically compatible, though the amber glass coating on the NA variants affects light color output.
All three bulb types conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical specifications across the North American market.
Front turn signal years calling for the 1034NA include 1968, 1969, 1972, 1974, and 1976, while years calling for the 1157NA include 1970, 1971, 1973, and 1975, reflecting a non-sequential alternation between the two amber variants.
