I would like to add blinkers (turn indicators) to my Camino and would be glad for inspiration because I ran into some troubles...
It already had the blinker switch on the handlebar and the cables, so I thought this would not be a great deal... but I was wrong.
I bought the blinkers themselves, managed to attach them to the Camino, connected them to the wires which should be right and, hey, when I press the switch the blinker goes on! But it did not blink.
So I figured out I need a blinker relay, got a matching one (6V 21W*2 max.) and finally found out where to add it in between. Result: when I press the switch the blinker goes bright, then it goes darker (but not completely off), then it goes on again. And when I brake the blinker goes off.
So I think I have two problems:
1. I think the blinker relay does not work properly on AC power (which comes from the generator), so I might need a rectifier. Right?
2. The generator does not have enough power to feed the brake light AND the blinker, so I need some extra power.
I had the idea to run the blinkers with 4x AA batteries = 6V. DC current, independent from the generator, problem solved. But then I started to calculate: 6V 21W*2 = 7 Amperes - this would discharge the batteries in something like 20 minutes, if the batteries can provide 7A at all before melting down or exploding

Probably the best solution would be to add a rectifier and a voltage stabilizer and use all this to charge a 6V rechargeable battery pack which can handle 7A current. But is this really necessary? I would be glad to hear of a simpler solution.
