Features:
1.Battery type recognition, different battery provides different output
2.Automatically shift down: When use lithium batteries, voltage is below 2.75V, WK42 turns off automatically.
3. High efficiency constant current driver circuit.
4.Click the switch to change between lighting modes, Double click the switch to access and change between the signal modes. In either signal mode, pressing the switch once changes to Low mode.
