    If the current rating of TR1 permits, connect a relay to it and use the relay contacts to control the lamp.

    The original Ultrasonic Radar project has two darlington-connected transistors at the output for driving the relay that he needs on his project.

    Uh.. yeah, I think I've seen it. I could swear that I gave him a relay driver circuit complete with interface to his circuit. :confused::rolleyes:
