The Trigger Accessory Control System substantially saves installation time of your electronic accessories! Eliminate the need to run wires under the dash or through the firewall of your vehicle when running wires. Our Bluetooth App will control on/off and dimming functions as well as flashing when used with LED or conventional lighting. It is simple to set up and allows for user customization. Use the app to “Trigger” lights from outside the vehicle whenever you might need to activate an accessory on demand. In addition to the app, Trigger includes an RF remote control for activating installed accessories from outside the vehicle and dimming/flashing functions for installed lighting. In addition, two 30 amp and two 10 amp fused circuits with LED indicators notify you of blown fuses. App Setup Instructions: 1.
