The Dodge Monaco brake components utilize 2057 and 1157 and 1034 bulb sizes for various lighting applications across the vehicle. Data for the specific lighting requirements covers the period from 1965 through 1992.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Monaco brake bulb specifications cover model years 1965 through 1992, with three distinct bulb types used across that span: the 1034, 1157, and 2057.
The 1157 is the most frequently specified brake bulb in the Dodge Monaco lineup, covering model years 1969-1978. It is a dual-filament ANSI-standard bulb rated at 12V with a 21W high-filament and 5W low-filament output, mounted on a BAY15d bayonet base.
The 2057 replaces the 1157 for the 1990-1992 Dodge Monaco brake light application. Both bulbs share the BAY15d bayonet base, but the 2057 operates at a higher wattage of 26.9W on its primary filament, making it the brighter of the two.
Although the 2057 and 1157 share the same BAY15d base type, their differing wattage ratings indicate they are not identical in output, and substituting one for the other may affect brake light brightness.
The 1034 is specified for model years 1965-1968. It shares the BAY15d bayonet base and a 12V, 21W/5W dual-filament configuration with the 1157, classifying it as a variant of that bulb type.
The center high mount stop light (CHMSL) is specified only for the 1990-1992 model years. The 1991 and 1992 models use the 912 bulb, while the 1990 model uses the 1156.
The 1156 specified for the 1990 Dodge Monaco CHMSL is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W. Its single-filament design and BA15s base distinguish it from the dual-filament BAY15d bulbs used in the standard brake light positions.
The 912 bulb used in the 1991-1992 CHMSL is a T15 wedge-type bulb rated at 12V and 12W. Its wedge base makes it physically incompatible with the bayonet-base bulbs used elsewhere in the Monaco brake light system.
The shift from the 1156 to the 912 between the 1990 and 1991 model years for the CHMSL represents a change in both base type and wattage, meaning the two bulbs are not interchangeable despite serving the same lamp position.
All bulb types specified across the Dodge Monaco brake light positions conform to ANSI standards applicable in both the United States and Canada.
