I recently ordered, received, and had installed a "Busch&Müller 4DToplight Senso Multi" dynamo tail light:




However, I was unpleasantly surprised to find that it apparently is rather inadequate as a dymamo rear light. As far as I can tell, it only has 3 settings:
1. Off
2. Dynamo Powered (turns off when the wheel stops spinning, though, so no standlight).
3. Always on (runs off batteries if wheel isn't spinning). Doesn't ever turn off until you flip the switch to #1 or #2.

It's wired up through a Lumotec Cyo front light.

Does anyone else own one - am I missing something? Is there a way to get it to act like a dynamo light with a standlight - turning on when the bike starts moving, and turning off automatically several minutes after the bike stops moving?

Please? :-) The only other alternative I have at the moment is this ugly ass tail light:

(edited so it's not confusing - the above pic is the light I currently have)

P.S. Also, is everyone elses switch on the light really flimsy and difficult to get into the middle position without accidentally leaving it in one of the other positions? It seem real finicky.
