The Eagle Premier brake light requires a 2057 bulb size for proper installation and function within the rear lighting assembly. Data for the specific component covers the period from 1988 to 1992.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Eagle Premier uses the 2057 bulb for the brake lights across all model years from 1988-1992.
The 2057 is a dual-filament bulb operating at 12V with a BAY15d bayonet base, drawing 26.9W on the high-intensity filament and 8W on the low-intensity filament.
As a brighter variant of the 1157, the 2057 delivers higher output on its primary filament while sharing the same BAY15d base type, which means physical fitment between the two may be possible, though output characteristics differ.
The center high mount stop light on the Eagle Premier uses the 1156 bulb for model years 1988-1991, then changes to the 912 bulb for the 1992 model year.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W, dedicated solely to stop light function given its single-filament design.
The 912 is a wedge-style T15 bulb rated at 12V and 12W, representing a notably lower wattage than the 1156 it replaced in the center high mount stop light position for the 1992 model year.
The 912 is a variant of the 921 bulb and uses a wedge base rather than a bayonet base, making it physically incompatible with the BA15s socket used by the 1156 in earlier model years.
All three bulb types listed in these specifications conform to ANSI standards applicable in both the United States and Canada.
