When you use it for the first time, unscrew the lamp cover and turn the switch to the “ON” position. When it’s tightened, be aware to lay the waterproof seal ring on the flat position. Otherwise, the water and air oxidation will enter it and may lead to electronic failure.
Sometimes the reason why the light can’t be turned on is that the collision may lead to the poor connection to the battery rather than the dead battery. Please make sure that the positive and negative electrodes of the battery are in good contact.
