Self-luminous, no switch required, 100% waterproof.

When installing, please align the positive and negative poles correctly, and the non-character end faces the spring 2: Be sure to put the battery into the black insulating holster inside, do not expose it, otherwise the battery and the lamp shell metal short circuit will cause the battery to discharge and heat, and it will be offline after a few minutes. 3: Pay attention when screwing the lamp cap. Make sure that the metal strip at the notch on the edge of the lamp holder is in good contact with the metal base (for example, if the metal is too close to the inside, you can manually remove it a bit, but it must be light!) 4: If the air fire wheel does not light up under normal conditions, adjust the length of the spring to ensure full contact with the battery (do not use excessive force, the spring is easy to fall), otherwise it cannot be turned on.
