Abstract
A flashing dart has a hollow barrel, a point assembly, a transparent shaft, a circuit board, a battery and a resilient element. The barrel has a front end and a rear end and is made of conductive material. The point assembly is attached to the front end of the barrel. The transparent flight shaft is attached to the rear end of the barrel. The circuit board has an integrated circuit controller and is firmly mounted inside the barrel. The battery has two electrodes connected respectively to the barrel and the circuit board. The resilient element abuts the battery and allows the battery to be temporarily disconnected from the circuit board when the flashing dart strikes a dartboard or is thrown thereby activating the integrated circuit controller that causes the lighting element to emit light for a preset period of time.
