Dodge Dynasty brake bulbs utilize 3157 and 3057 sizes, while the center high mount stop light requires a 922 bulb size. The replacement chart covers vehicle production spanning 1988 to 1993.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Dynasty uses three bulb types across its brake light positions: the 3157, the 3057, and the 922, all of which conform to ANSI standards recognized in both the United States and Canada.
The 3157 and 3057 are both dual-filament wedge bulbs sharing the T25 form factor, rated at 12V with a 27W/7W output, where the higher wattage filament serves the stop function and the lower wattage filament serves the tail or running light function.
Despite their near-identical specifications, the 3157 and 3057 are not the same bulb. The 3057 uses an asymmetric base pin configuration, while the 3157 uses a symmetric one, meaning the two are not directly interchangeable without verifying socket compatibility.
The Dodge Dynasty (1988-1991) uses the 3057 bulb for the standard brake lights, while the 1992-1993 model years use the 3157 in that same position.
The 922 is a single-filament wedge bulb in the T15 form factor, rated at 12V and 16W, and it serves the Center High Mount Stop Light (CHMSL) across all Dodge Dynasty model years from 1988-1993.
The T15 form factor of the 922 bulb is physically smaller than the T25 form factor shared by the 3157 and 3057, making the 922 incompatible with the sockets designed for the standard brake light positions.
Because the CHMSL requires only a single-filament bulb, the 922 lacks the secondary low-wattage filament found in the 3157 and 3057, reflecting the CHMSL's dedicated stop-light-only function with no tail light role.
