The Buick Park Avenue brake light utilizes 3057 and 2057 bulb sizes for the rear lighting system. Available information covers the production period starting in 1991 and ending in 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Buick Park Avenue uses the 3057 bulb for the brake light across the 1992-2005 model years, making it the most consistently specified bulb in these specifications.
The 3057 is a dual-filament wedge bulb operating at 12V with a high-intensity filament rated at 27W and a low-intensity filament rated at 7W, a configuration typical of combination stop and tail light applications.
The 1991 Buick Park Avenue brake light takes a 2057 bulb rather than the 3057 used in all subsequent model years. These two bulbs share a dual-filament design but differ in base type: the 3057 uses a wedge base while the 2057 uses a BAY15d bayonet base, making them physically non-interchangeable.
The center high mount stop light (CHMSL) on the Park Avenue uses the 1156 bulb for the 1991-1992 and 1994-2005 model years.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W. Its single-filament design reflects its dedicated stop light function, which requires no secondary low-intensity circuit.
The 1993 Park Avenue CHMSL takes a 1141 bulb rather than the 1156 used in surrounding model years. Both the 1141 and 1156 share the same BA15s bayonet base and identical 12V, 21W ratings, which means the two bulbs are electrically equivalent and physically compatible with the same socket.
All four bulb types listed in these specifications conform to ANSI standards recognized in both the United States and Canada, indicating standardized electrical and physical tolerances across the range.
