An Improved method of marking locations and obstacles in low light situations comprised of an LED, with an integral resistor to allow it to be powered from a 9 vdc source, that is connected, via the anode and the cathode, to a pair of battery terminals. These terminals allow it to be attached to a conventional 9 volt battery. The terminals are affixed to a base that the LED sits upon. The base is covered with a cap that prevents any movement of the LED.
