The Chevrolet Lumina APV front turn signal bulb size measures 3157NA or 3057NA, while the rear turn signal bulb size measures 2057. The replacement chart covers 1990 through 1996 vehicle 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 Chevrolet Lumina APV uses three distinct bulb types across its front and rear turn signal positions for the 1990-1996 model years: the 3157NA, the 3057NA, and the 2057.
The 3157NA and 3057NA are both ANSI-standard dual-filament wedge bulbs in the T25 form factor, rated at 12V with a 27W high filament and 7W low filament, and both feature natural amber glass that produces a yellow-orange light output without the need for an amber lens.
The front turn signal position on the Chevrolet Lumina APV transitioned from the 3057NA to the 3157NA between the 1992 and 1994 model years, with the 3057NA fitted to 1990-1993 models and the 3157NA fitted to 1994-1996 models.
Although the 3157NA and 3057NA share the same T25 wedge base and identical voltage and wattage ratings, they are not fully interchangeable in all applications, as their internal filament configurations differ in ways that affect compatibility with certain socket designs.
The rear turn signal position uses the 2057 bulb across all model years from 1990-1996, making it the only turn signal position with no change in bulb specification across the full production run.
The 2057 bulb uses a BAY15d bayonet base rather than a wedge base, which physically distinguishes it from the front turn signal bulbs and prevents cross-position substitution.
The 2057 is a dual-filament bulb rated at 12V, 26.9W high filament and 8W low filament, and it is a brighter variant of the widely used 1157, meaning the two share the same BAY15d base but are not identical in output.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating they meet a common regulatory baseline for automotive lighting in North American markets.
