  • "The D1 gives out 5V DC and shouldn't be used with dynamo lights. " :/

  • I think that's saying that you can't run the dynamo lights off the 5VDC output from the D1. If you look in the manual it says

    Where you are running dynamo lights, you can 'piggyback' off your
    current wiring, but don't connect the D1 to a regulator – it should
    get it's power direct from the dynamo. Research the specification for
    your current lights to see how they regulate the extra dynamo power.
    Most 'dump' anything over 6V as heat, but the D1 uses this extra
    capacity to provide greater output at higher speeds.
