Additional Notes

The 3157 is the specified back up light bulb size for the Chrysler Prowler across its 2001-2002 model years.
The 3157 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard used in both the United States and Canada.
The 3157 is a dual-filament bulb, housing two separate filaments within a single unit. One filament operates at 27W and the other at 7W, allowing the bulb to serve two distinct lighting functions at different brightness levels.
The 3157 follows a T25 wedge form factor. The T25 designation refers to the bulb's tubular shape, with the number indicating its width in eighths of an inch, and the wedge base type means it is held in place by the socket itself rather than by a separate locking mechanism.
The 3157 operates on a 12V electrical system, which is standard for passenger vehicles of this type.
Because the 3157 is a dual-filament bulb, substitution with a single-filament equivalent would result in the loss of one lighting function. Fitment of a physically similar but electrically different bulb risks incorrect operation of the back up light circuit.
