Home Made Level Crossing Alarm and lights 

Working on a project to make my own level crossing alarm ad lights using generally available circuit components and a little bit of experimentation, this is part 1, modifying the first set of Hornby level crossing lights. (these come as just plastic components with no lights in so drilled the out, fitted small LEDS and wired to a flip flop circuit with attached alarm. plan is to have orange one coming on first and then an infrared sensor starting and stopping the sequence as the train passes.
