So in all my years in motorcycles and generally working on vehicles I've not seen a three wire tail light ? Why did they do that ? Can I convert it ? I've messed a round with grounding the casing but that doesn't work . All after market tail lights / that id like to use Re two wire and I can't seem to get that to work . Help

I think a wire each for brake, running, and ground. Considering almost everything mounted to the frame (except the engine) has rubber bushings, maybe that's the reason for the ground wire.
Or I could be totally full of it. I'm sure a Guru will pipe up about this soon.

Dan, you are absolutely correct. Jkling, I use an aftermarket 2-wire tail light, and the solution was simple. I crimped a 5 mm. ID ring connector on one end of the OE ground wire and attached it to the socket plate of the new tail light using one of the screws that secure the socket plate to the housing. I left the other end plugged into harness ground. If that procedure doesn't work for you, break out your multitester and find out why.

I don't know what bike, but a lot of bikes have tail lights mounted in rubber, hence the need for a ground wire. Japanese msnufacturers tend to have an earthing loom where everything that needs to be earthed is earthed to a common point. Better than having a dozen earthing points for fault finding.
