Installation precautions and common problem solving:

1: Hot Wheels uses three AG10 batteries (included), please align the positive and negative poles accurately when installing, and the end without words faces the spring

2: Be sure to put the battery in the blainsulating inside, do not expose it, otherwise the battery and the metal of the lamp housing will be short-circuited, which will cause the battery to discharge and heat up, and it will be dead in a few minutes.

3: Be careful when twisting the lamp head, and make sure that the metal strip in the gap on the edge of the lamp head is in good contact with the metal base (if the metal is too close, you can manually pull it out a little, but it must be light!)

4: If the hot wheel does not light up under normal conditions, you can adjust the length of the spring to ensure that it can fully contact the battery (do not use too much force, it is easy to cause the spring to fall off), if it still does not light up, go to step 3
