thanks for the reply and the bike pic!
I understand the appeal of the symmetry of running two lights, and perhaps just the exotic aspect of it.
The Schmidt products have been very well engineered and built, so they are bits of bike jewelry all by themselves (and I've got two Schmidt hub dynamos). If this keeps two of these headlights in use, then I'm all for it. In fact, I've got some of the 3 watt flanged bulbs that need a new home, in case you are interested and can use them.

As an electrical engineer that rides bikes and has designed my own lights for quite a while, I love the new technologies but still love the aesthetics of some of the old lights. A few of the old lights lend themselves to being retrofitted with new technology, but for the headlights, it ends up being rather difficult to do well. So.. I'm glad to see these E6's continue to be used, but I'm also wondering if there is a way to sneak some new technology into the housing. The usual answer is "yes, but it costs more than it's worth". I'm intrigued by the idea, but it's Off Topic for this forum, and probably not something that anyone would want to pursue.

Thanks for sharing the info on the project and the bike photos!
