Hi David, <br /> <br />I have a similar problem. I would like to have a circuit design to start and stop blinking lights at road crossings. However, I would like to purchase the actual electronics from an outfit like Digi-Key etc. because purchasing them from hobby suppliers is TOO expensive if one has many crossings. I have purchased photocells from Radio Shack. As light is on or off to the cells the resistance changes, I believe. One would have to design a circuit to turn on the blinking lights then control the blinking - maybe adjust the speed of the blinks. <br /> <br />If you find a solution to your question, please e-mail me, OK?? <br /> <br />Regards, <br /> <br />Frank Eder
