The Dodge Caravan brake light utilizes 3057, 3157, 2458, and 2057 bulb sizes depending on the specific production period for the vehicle. Available data covers the range from 1984 through 2007 for the components listed.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Caravan brake lights rely on three bulb types across the full model range: the 3057, 3157, and 2057. All three conform to ANSI standards recognized in both the United States and Canada.
The 3057 is the most widely used brake bulb in these specifications, covering the 1996-2007 model years. It is a dual-filament wedge bulb in the T25 form factor, rated at 12V with a 27W high filament and a 7W low filament.
The dual-filament design of the 3057 allows a single bulb to serve both the brake light function and a lower-intensity running light function, which is typical for combination tail and stop lamp assemblies.
The 3157 shares the same T25 wedge form factor and identical 12V, 27W/7W electrical ratings as the 3057, yet the two are not interchangeable in all sockets. The 3057 and 3157 differ in their indexing tab positions, meaning a 3157 socket will not accept a 3057 without modification, and vice versa.
The 1993-1995 Dodge Caravan uses the 3157 for the brake light position. Despite the near-identical specifications to the 3057, the socket design difference makes fitment year-specific.
The 1984-1988 Caravan uses the 2057, a dual-filament bulb with a BAY15d bayonet base rather than a wedge base. This base type is physically distinct from the T25 wedge used in later model years, making the 2057 incompatible with sockets designed for the 3057 or 3157.
The 2057 is rated at 12V, 26.9W/8W and is described as a brighter variant of the 1157. The slightly higher wattage on the low filament compared to the 3057 and 3157 reflects a minor electrical difference between the bayonet-base and wedge-base generations.
The center high mount stop light (CHMSL) on the 1996-2007 Caravan uses the 921, a single-filament T15 wedge bulb rated at 12V and 16W. Single-filament construction is standard for CHMSL applications, as the lamp serves only one function.
The 1993-1995 Caravan CHMSL uses the 922 instead of the 921. Both are T15 wedge bulbs with identical 12V, 16W ratings, and the two types are generally considered interchangeable in practice, though the specifications list them separately by year.
No CHMSL specification is listed for the 1984-1988 model years, which aligns with the fact that the CHMSL became a federally mandated requirement for passenger vehicles in the United States starting with the 1986 model year for cars, with light trucks and vans following under separate rulemaking timelines.
