Describe  1: Hot Wheels uses its own battery, please align the positive and negative poles accurately when installing, and the end without letters faces the spring  2: Be sure to put the battery in the black insulating holster inside, do not expose it, otherwise the metal short circuit between the battery and the lamp shell will cause the battery to discharge and heat, and it will soon be out of power.  3: Be careful when twisting the lamp cap, and make sure that the metal strip in the notch on the side of the lamp cap is in good contact with the metal base (if the metal is too close, you can manually pull it out, but it must be light!)  4: If it does not light up under normal conditions, you can adjust the length of the spring to ensure full contact with the battery (not too hard, which may cause the spring to fall off)  Specification  Name: Car and bicycle accessories tire light  Material: plastic + electronic components  Category: Tire Light  Power supply: 3 AG10 button batteries  Color: color, blue, red, green  Size: about 3.8cm  Application: cars, motorcycles, bicycles  Package includes: 1* tire light
