An access control gate for parking lots includes an access gate main body with a built-in actuating device and a gate arm that is coupled to the gate control device of the access gate main body where the actuation of the actuating device controls the movements of the gate arm. The gate arm can be mechanically connected to or removed from the access gate main body. The gate arm has a light-emitting device (LED) installed longitudinally on one side. The joint structure connecting the gate arm and the access gate main body will immediately release the gate arm from the access gate main body and disconnects the electricity connecting to the LED upon an abnormal impact, such as a vehicle collides with the gate arm.
