Unless your lucky enough to own one of the first 100 games produced prior to this feature being axed to save production costs! I'd rather my Dalek topper did a bit more then sit there for 90% of the time doing nothing! So my mod will pulsate a 3W led to simulate a breathing Dalek , however when triggered by the original flasher lamp the topper sweeps left to right then reverts to its home position. Whilst moving the Dalek lights will flash just as the original flasher lamp would have before reverting back to the breathing mode. This PCB can be used to initially control the LED in the Dalek and at a later date you could implement the motor side. You will just be buying the PCB from me, assembled with instructions and guidance notes, please read them at my website NOT A COMPLETE PLUG AND PLAY MOD KIT you will need to make brackets etc to fit the LED & motor and wire into existing pinball wiring.
