Ok,

I'm getting to the point where I'll be setting up a Generator/Dynamo on a couple of touring/commuting bikes... I hope.

Does anybody know of flashing/blinking generator taillights?

I really don't want to do pure rechargeables if I'm setting up the genset. Nor do I like steady red lights.

I suppose there is the Reelight, but that would be an additional form of redundancy, and I'm seeing mixed reviews on it.

It should, of course, also have the ability to stay on for a couple of minutes.

I believe at least some of the Genset technology is coming from Germany which may prohibit blinking lights.
