DC Dusk-to-Dawn Light Sensor Switch 3.7-24 V, 5 A

✅ Let darkness switch it. The night-on module responds when ambient light falls and returns to off in daylight.

✅ Skip the timer. Light sensing follows the changing daylight instead of a fixed clock setting.

✅ Wire a DC circuit. Separate input and lamp leads give the connection points for a compatible low-voltage setup.

✅ Match the load. Check lamp load, voltage and polarity against the module and its wiring diagram.

Ambient light control for a low-voltage lighting circuit

An inline dusk-to-dawn sensor module for DC 3.7-24 V lighting circuits. It switches a compatible lamp on as light levels fall and off again in daylight, with a stated maximum current of 5 A. One module is supplied, and the lamp, battery and power adapter are not included.

Check your DC circuit and add automatic dusk-to-dawn control.
