Dodge Daytona Back Up Light Bulb Size

The Dodge Daytona back up light requires a bulb in 3157, 3057, or 1156 size depending on the specific vehicle configuration. A replacement chart covering 1984 to 1993 model years documents the bulb specifications for this application.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Dodge Daytona back up light bulb specifications span the 1984-1993 model years, covering three distinct bulb types across that range.
The 1156 bulb was used in the Dodge Daytona from 1984-1988. It is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W under the ANSI standard applicable in the US and Canada.
The BA15s bayonet base on the 1156 bulb features a single contact pin, which physically distinguishes it from dual-contact bayonet bases and makes it incompatible with bulbs that use those bases.
The 3057 bulb was used from 1989-1990 and again in 1991. It is a dual-filament wedge bulb in the T25 form factor, rated at 12V with filaments drawing 27W and 7W respectively, and it conforms to the ANSI standard for the US and Canada.
The 3157 bulb was used from 1992-1993. It shares the same T25 wedge form factor and 12V, 27W/7W dual-filament rating as the 3057, and it also conforms to the same ANSI standard.
Although the 3057 and 3157 share identical voltage and wattage ratings and the same T25 wedge form factor, they are not confirmed interchangeable in these specifications. The Daytona uses each in distinct model year groups, and substituting one for the other without verification of socket compatibility is not supported by the listed data.
The transition from the 1156 single-filament bayonet bulb to the 3057 dual-filament wedge bulb between the 1988 and 1989 model years represents a change in both base type and filament configuration, meaning the two bulb types are physically incompatible with each other's sockets.
The dual-filament design of the 3057 and 3157 bulbs means each contains two separate filaments operating at different wattages, a feature that allows a single bulb to serve more than one lighting function in other applications, though in this context they are specified solely for the back up light position.
The 1156, 3057, and 3157 bulbs all operate at 12V, consistent with the standard electrical system voltage of passenger vehicles produced during the Daytona's production run.
All three bulb types in these specifications conform to ANSI standards recognized in both the US and Canada, indicating they meet a defined set of dimensional and performance criteria for those markets.
