This circuit allows cyclists to indicate that they are making a turn without taking their hands off the handlebar. The user activates the flashing amber turn signals by using the control switches mounted on the handler bar with their fingers thus eliminating the use of hand signals. This circuit is useful when riding at night owing to it’s flashing red LED taillights, headlights and flashing amber signal LED’s visually displaying the cyclists intention to surrounding vehicles thus preventing accidents and injuries to the cyclist.

Bad design. Two switches needed for a single indicator.

@voluharw, in real life it would not be Two switches it would be one switch with a centre off position, unfortunately EC does not have this component, so two switches are required to simulate this function. My only critique is, the flash rate of the tail lights is too slow, get rid of the Counter and And Gate, just use the fet to drive the lights straight from the 555 resistor. Try this circuit; http://everycircuit.com/circuit/5433915433811968

@BillyT your design is much better without the counter and the And gate. However, I would use LM556 dual 555 timer for different blinking frequency of tail light and indicators.

@voluharw, I did think of that, but I presented that circuit for simplicity and to fit in the space available.

Thank you very much for the feedback, I’ve made a few changes following @BillyT’s simplicity idea...
