Flash Valve Core

People used to check if the bicycle tire needs to be inflated by pressing it by hand. If It can be out of shape or flattened easily, that means the tire pressure is too low and you need to inflate it immediately. Now the flash valve core offer you a more convenient and clear way to inform you if the tire needs to be inflated. The valve core can detect the tire pressure and if the tire pressure decrease, the light turns from green to red. Also, the light can provide a safer riding at night.
