The headlamp features two buttons on the top - one on the right that activates and deactivates the auto sensor, and one on the left that allows you to switch between white light (with options for strong, weak, and SOS) and red light (long pressing for strong/SOS) to suit different environments. Additionally, the motion sensor button allows you to easily turn the white light on or off by simply waving your hand within 10cm of the headlamp, adding an extra level of convenience.
