Lights

Does anyone know a way to quick release dynamo lights? I've seen the QR bolts but the wire is the problem since it is fixed to the light.

I'll soon have 2 bikes with dynamo hubs and would rather not have to rewire all the time. I have a good light I'd like to use it on both bikes instead of forking out for a second one. It would also help to prevent theft.

I guess a normal spade connector could work but those are usually shrink wrapped to keep out rain - not sure if it would be good to expose the electrical connection to the elements?

Depends upon the dynamo hub you're using. Many, like Shimano, have a plastic block that you pass the wired into - when this block is pushed over its mate on the hub, the contact is made, but it's fairly waterproof and the holes for the wires usually have a bit of liquid silicone in them to seal them. Others use spade connectors with heat-shrunk covers; I suspect that they're all right as long as the two contacts aren't bridged by a water droplet...
