Additional Notes

The 3157 is the tail light bulb size for the International HX520 across the 2018-2019 model years.
The 3157 bulb follows the ANSI standard, which governs bulb specifications in the United States and Canada, ensuring consistent performance and fitment across compliant applications.
This bulb uses a dual-filament design, meaning a single unit serves two brightness levels within the same housing, typically one filament for running light function and one for braking.
The T25 designation refers to the wedge-style base of the bulb, a form factor that seats directly into a socket without a separate bayonet or screw mechanism.
The 3157 operates at 12 volts, consistent with standard automotive electrical systems.
The wattage rating of 27W/7W corresponds to the two filaments, with the higher draw assigned to the stop function and the lower draw to the tail or running light function.
