Default Re: Your first experience with LEDs?

My first LED was in a watch of which I was mightily proud as it seemed to futuristic. One point about car/bike ignition systsm is I have allways wondered why they do not use some variant of the pizeo electric ignition buttons as on gas torches or barbecues. Surely some sort of drive off the car timing belt and cam operating a pizeo button could achieve the spark with using a battery or electronics (save for the pizeo circuit) at all.
