1. When installing the battery, be sure to lower the positive pole (the side with words is the positive pole). Do not remove the insulating transparent plastic sheet inside the lamp shell, which is used to prevent the short circuit between the battery and the metal of the lamp shell, otherwise, the metal short circuit between the battery and the lamp shell will cause the battery to discharge and heat up, and the battery will run out of power in a few minutes.

2, it is normal that the circuit board inside the lamp holder is loose. Be careful not to let the circuit board fall when removing the lamp holder!

3, this price is a single price, generally a bicycle or motorcycle can be configured with 2, car configuration 4.
