Dynamos für die Fahrradbeleuchtung: Unterschied zwischen den Versionen

Don’t mix up the two wires!  Some folks have double-wired as above, but connected the “hot” wire to ground.  Everything will look fine, but you'll get no light!  Pay careful attention to the two different colors of your wires, and to where each is connected.

Control your wires.  Straighten them before installing them - no kinks or bends - and run them in a neat line, perhaps along the back edge of the fork, or following the brake or shift cables.  Use zip ties to keep them tight to the frame, or to tie them to the cable housings.  Leave just enough slack at the proper place to let the forks pivot. The illustration below shows wiring of a Shimano generator.

Hub generators need a switch.  Since the magnets are always rotating with the hub, it’s normal for hub generator headlights to have an on-off switch.  If you wish to use a non-switched headlight, your choices are to either add a switch to the circuit or to always ride with the light on - a Daytime Running Light.  Bottles and rollers don’t need a switch.

Then trade the favor with your friend.  You'll be glad you did!
