The Dodge Grand Caravan brake light uses 3157, 3057, 2458, and 2057 bulb sizes depending on the specific production period for the vehicle. Data for the lighting components covers the range from 1987 through 2010.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Grand Caravan brake light circuit uses three distinct bulb types across its model history: the 3157, 3057, and 2057 for the main brake lights, and the 921 or 922 for the center high mount stop light.
The 3057 and 3157 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. Despite their near-identical specifications, they are not considered interchangeable due to differences in filament positioning within the base.
The Dodge Grand Caravan (1996-2007) uses the 3057 for the main brake lights, making it the most frequently specified bulb across the model's history in these specifications.
The 3157 is specified for the main brake lights on the 1991-1995 and 2008-2010 Grand Caravan, placing it at both ends of the covered model range.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 26.9W high filament and 8W low filament. Its bayonet base makes it physically incompatible with the wedge sockets used by the 3057 and 3157.
The 1987-1990 Grand Caravan uses the 2057, which carries a BAY15d bayonet base rather than a wedge base, meaning it requires a different socket type than all later model years covered in these specifications.
The 921 and 922 are both ANSI-standard single-filament T15 wedge bulbs rated at 12V and 16W. Their shared wattage and form factor place them in the same functional category, though they carry different ANSI designations.
The center high mount stop light on the 1993-1995 Grand Caravan uses the 922, while the 1991-1992 and 1996-2007 model years use the 921 for the same position.
The 921 is the most widely specified bulb for the center high mount stop light, covering the 1991-1992 and 1996-2007 Grand Caravan in these specifications.
All bulb types listed in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating consistent regulatory compliance across the covered model range.
