NAPA Horn Relay

If your horn won’t engage or clicks without sound, the NAPA Horn Relay may be the missing link. This electromechanical relay serves as a bridge between the low-power horn switch and the high-power horn unit, enabling reliable signal transmission without overloading the switch circuit. Frequently installed in under-hood relay centers, the NAPA HR101 also supports auxiliary functions like driving lights, fans, or aftermarket audio systems.
