• 【HEAVY DUTY PERFORMANCE】Engineered for demanding automotive applications. Each relay handles high continuous 40Amp current, ensuring safe and reliable power delivery to your 12V accessories. The compact 2-button remote allows you to control two separate circuits (one for each relay) effortlessly from inside or outside the vehicle
• 【BUILT-IN DIODE & ANTI-INTERFERENCE】Unlike basic relays, ours features an integrated printed circuit board (PCB) with a protective diode. This prevents voltage spikes from damaging sensitive vehicle electronics and ensures stable, long-distance remote signal reception without cross-talk
• 【LONG-RANGE CONTROL】Operating on a highly stable 433MHz frequency, it delivers robust anti-interference performance without cross-talk. Enjoy seamless wireless operation with an impressive remote range of up to 164ft in open areas
• 【CRUCIAL WIRING TIP FOR UPGRADES】When replacing an existing relay, the relay's receiver needs power to work. Option 1: Keep your original physical dash switch in the "ON" position to supply power to the relay, then use the remote to trigger the device. Option 2: For independent remote control, bypass the original switch to provide constant 12V power to the relay coil. (Not support the simultaneous operation of the power switch and remote control)
• 【LIMITLESS 12V APPLICATIONS】Go far beyond just off-road light bars. This wireless relay kit is the solution for upgrading 12V accessory. Perfect for Automotive (cooling fans, train horns, air compressors), RVs & Campers (water pumps, awning controls, exterior lighting), Marine Boats (bilge pumps, deck lights), and ATV/UTVs. Enjoy remote control without ever drilling through your firewall or running messy wires into the cabin
