Additional Notes

The Chevrolet C-Series Pickup uses the 2357NA bulb for its parking light across the 1988-2000 model years, with the sole exception of 1992, making it the most consistently specified bulb in these fitment records.
The 2357NA is a dual-filament bulb rated at 12V and 26.9W/8W, fitted with a BAY15d bayonet base and natural amber glass, conforming to ANSI standards for the US and Canadian markets.
The natural amber glass in the 2357NA produces an amber-tinted output directly from the bulb, which eliminates the need for an amber-tinted lens to achieve a legally compliant turn signal color in applicable markets.
The 1992 model year is specified with the 3057 rather than the 2357NA. The 3057 is a dual-filament wedge-type bulb (T25) rated at 12V and 27W/7W, and it does not carry the natural amber designation, meaning its glass is clear.
The 1985 and 1986 model years each carry two separate fitments depending on headlamp configuration. Vehicles with two headlamps use the 3057NA, while those with four headlamps use the 2057NA, indicating that headlamp count is a critical compatibility factor for those years.
The 2057NA shares the BAY15d bayonet base and natural amber glass of the 2357NA but is described as a brighter variant of the 1157, rated at 12V and 26.9W/8W. The 3057NA carries the same wattage rating (27W/7W) as the 3057 but adds the natural amber glass coating.
The 1983-1984 model years are specified with the 2057NA across all configurations, placing this bulb type in use on the C-Series Pickup before the 2357NA became the dominant fitment.
The BAY15d bayonet base is shared across the 2357NA, 2057NA, 1034NA, 1157, and 1157NA bulb types. Despite this shared base, these bulbs are not freely interchangeable, as they differ in wattage output and glass tint.
The 1979 and 1982 model years use the 1034NA, a dual-filament BAY15d bulb with natural amber glass rated at 12V and 21W/5W. This wattage output is lower than that of the 2357NA and 2057NA used in later years.
The 1975-1978 model years are specified with the 198, a miniature wedge bulb (T5) rated at only 12V and 2W. This output is substantially lower than all other bulb types found elsewhere in these specifications, reflecting a distinct lighting design for those earlier model years.
