Additional Notes

The International HX515 uses the 3157 bulb for its tail lights across the 2017-2019 model years.
The 3157 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 3157 is a dual-filament bulb, which allows it to serve two lighting functions within a single unit, typically a brighter output for stop or turn signals and a dimmer output for running lights.
The bulb operates on a 12-volt electrical system, consistent with standard automotive DC voltage.
The two filaments in the 3157 are rated at 27 watts and 7 watts respectively, reflecting the difference in brightness between its two operating modes.
The 3157 follows the T25 wedge form factor, a designation that refers to the shape and size of the bulb's base, which determines physical fitment into the socket.
Because the 3157 is a dual-filament type, substituting it with a single-filament bulb of a similar base style would result in the loss of one lighting function and is not a compatible replacement.
