Describe:1: Hot Wheel uses its own battery, please align the positive and negative poles accurately when installing, and the end without letters faces the spring2: Be sure to put the battery in the black insulating 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 e 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 acceories tire lightMaterial: plastic + electronic componentsCategory: Tire LightPower supply: on batteryColor: color, blue, red, greenSize: about 3.8cmApplication: cars, motorcycles, bicyclesPackage includes: 1* tire light
