The Plymouth Grand Voyager brake light utilizes 3057, 2458, 3157, and 2057 bulb sizes depending on the specific version of the vehicle. Data for the components covers the range from 1987 through 2000.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Grand Voyager uses three distinct brake bulb types across its model years: the 3057, 3157, and 2057 for the standard brake lights, and the 921 and 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 the same part number and are not listed as interchangeable within these specifications.
The Plymouth Grand Voyager (1996-2000) uses the 3057 bulb for the brake light, while the 1991-1995 model years use the 3157. Both share the same wattage and voltage ratings, but the part numbers differ.
The 2057 bulb, used in the 1987-1990 brake light position, features a BAY15d bayonet base rather than the wedge base found on the 3057 and 3157. This base type difference makes the 2057 physically incompatible with sockets designed for T25 wedge bulbs.
The 2057 is described as a brighter variant of the 1157, operating at 12V with a 26.9W high filament and 8W low filament. Its high-filament output is slightly lower than the 27W rating of the 3057 and 3157.
The Center High Mount Stop Light on the Grand Voyager uses single-filament T15 wedge bulbs, either the 921 or 922, both rated at 12V and 16W under ANSI standards.
The 921 is specified for the Center High Mount Stop Light in the 1991-1993 and 1996-2000 model years, while the 922 appears in the 1990, 1994, and 1995 model years. The 921 and 922 share identical voltage and wattage ratings within the T15 form factor.
Because the standard brake light socket type changes between the 1990 and 1991 model years (from BAY15d bayonet to T25 wedge), bulbs from the 1987-1990 fitment are not physically compatible with the 1991 and later positions.
