LED turn signal circuit question
« on: Jan 02, 2018, 18:46:40 »
Hey,

Just recently completed a budget build on my '74 cb360. The bike wiring was completely redone with minimal components and there is currently no turn signal circuit. I want to add some bar end LED signals but I am not sure of all the components needed to build the circuit from scratch. I do know I need a LED flasher relay but I read a bunch about needing to install inline diodes? Just wondering if anyone can shed a light on what would be needed for sure. Thanks!


p.s. - here's a pic of the bike:

An electronic flasher relay that can drive LED's doesn't require you to add-in a resistor.  You just need the handlebar switch, the lights, the relay, and I would put them on their own fused circuit.

+1 to what Eric said.

Further to the question about the diodes, those diodes are only necessary if you plan to use a dashboard indicator/warning light and again only if you're using just a single light to show either direction.

Gotcha! Thanks! I've attached a pic of my components. The LED turn signals didn't come with any info but I'm assuming the third wire is for a running light setting? I will probably clip that wire if so. Is there a simple circuit someone could link me to follow when hooking all this up? Just wondering where the relay wires in at. Thanks!

Power -> Flasher Relay -> Switch -> Light -> Ground

On a Honda, power would be a black wire, the turn signal would be orange or light blue (depending if left or right side), and ground is dark green.
