Indicator not blinking

[Real_Wolf]

yeah, i agree, studying various electronics I couldn't help but think a two light blink circuit would not be hard to make, mind you transistors did cost a bit more back then.

Heck, you could just buy an opamp and have it driven into critical oscillation with a step voltage, put a dc offset so the 'negative' is then 0, and run both lamps through that

it has always been a wonder to me why we still use mechanical relays for indicators; a 555 timer driving a BJT or MOSFET (rated accordingly, of course) would be a much cheaper and reliable solution. all the thumb switch has to do is select which light to ground.

You do, there's plenty of flasher `relays' just like this, fully electronic and they have a range in which they'll work. I've got one fitted to the cub, 6V, 8W-23W x2. So you can fit bulbs (front and rear) which are between 8W and 23W and it'll still flash at the normal rate. They're quite common in generic auto stores.

The only issue I have with it is that at high RPM the generator produces too much voltage and the flasher stops flashing.
