PaulRivers;

I was referring to the connection at the headlight, not at the dynamo. What you show is the standard Shimano dynamo connector. I figured that any true quick hookup/disconnect system for dynamo lighting should have the wiring harness on each bike left in place so only the dynamo wheel and lights need to be moved. Otherwise the lights and dynamo move requires rerouting of wiring on each bike to make the switch. I was trying to make the changeover be as quick and painless as possible.

As another poster noted current Dynamo systems are really intended for permanent mounting. If running both dynamo headlight and taillight the wiring harness needs to be set up IMO so that it remains in place on each bike and the lights need to be set up with both electrical and mechanical quick disconnects.

When set up with the factory wiring harness the Light On! headlight has both but the taillight does not. Due to normal bolt-on mounting dynamo taillights appear to be difficult to make quick change without some work.
