WebHow do light gates work? The vehicle with a card on top of it is released from its starting position and moves down the slope - the light beam is cut by the card as it enters the light gate and the timer starts - the beam remains cut until the back of the card passes out of the light gate - when the card leaves the gate, the beam stops the timer WebThe light gate measure how long the beam has been cut for.
