Plymouth Satellite front turn signal bulbs utilized 1157NA, 1157, or 1034 sizes, while rear turn signal bulbs used 1157 or 1034 sizes. The replacement chart covers 1965 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 Plymouth Satellite uses four distinct bulb types across its turn signal positions and model years: 1157, 1157NA, 1034, and 1034NA.
All four bulb types share the BAY15d bayonet base and a dual-filament configuration rated at 12V with a 21W/5W output, where the higher wattage filament serves the turn signal function and the lower wattage filament serves a secondary running light function.
The 1034 and 1034NA types are classified as variants of the 1157, meaning they share the same base type and general electrical characteristics while differing in other physical respects.
The NA suffix on the 1157NA and 1034NA designates natural amber glass, which produces an amber light output directly from the bulb rather than relying on a colored lens to filter white light.
The front turn signal of the Plymouth Satellite used the 1034NA for the 1965-1967 model years, the 1034 for 1968, the 1157 for 1969-1973, and the 1157NA for 1974.
The rear turn signal followed a slightly different pattern, with the 1034 used for 1965-1968 and the 1157 used for 1969-1974, with no NA-suffix variants specified for any rear position.
The front and rear turn signal positions used matching bulb types for most model years, with the 1974 front position being a notable exception where the 1157NA was specified rather than the standard 1157 used at the rear.
Because the 1034 and 1157 share the BAY15d base, physical installation between these types is possible, but their status as distinct ANSI-classified types means substitution may not satisfy original equipment specifications.
All four bulb types conform to ANSI standards applicable in both the United States and Canada.
