Busch & Muller IQ-X dynamo headlight
The appearance of simplicity extends to the light's operation: one Senso/off switch on the back of the lamp is the only control. The perimeter of the switch also glows a pleasant, if somewhat techy, blue, and along with slits on the side of the housing, should add side-on and rear-facing visibility. In Senso mode (engage Senso by leaving the switch in the on position,) the IQ-X provides a daytime running light which shifts to the super beam at dusk. A capacitor provides stand light. Includes mount and connection for tail light.
A neat and powerful headlight!
