The Radiance Multi-Trigger Harness was designed specifically for the RIGID Radiance light bar. Equipped with two independent circuits for an easy install, circuit one is designed for higher amperage and utilizes a relay to power the primary LEDs on the Radiance light bar while circuit two is designed for low amperage and has no relay for the backlighting circuit on the Radiance. The Radiance Multi-Trigger Harness also comes standard with two separate backlit LED rocker switches (red and blue), so each circuit can be used independently. The Radiance Multi-Trigger Harness makes installation of your RIGID Radiance as simple and clean as possible.
