Dipped:

Main & switch:

Aerial view:

It's a bit Heath Robinson but it's all solid. The switch I had to hand is totally unsuitable but I've got a heftier waterproof one coming in the post. I'll probably solder all the connections, as spade connectors usually corrode in the wet. It all needs tidying up but a short blast round the lanes was pretty successful - the edelux beam cuts off very sharply at the horizon so you don't see anything but the road, the solidlights is good for distance and lighting up trees, walls, houses though none of it is quite as bright per sq ft as the Edelux.
The switching between the two is superb - The switch is positioned to be easily flicked by a thumb, and I reckon a toggle that sticks out is better than a rocker switch. From main to dipped the solidlights goes off instantly, but from dipped to main the Edelux stays on for another second or two, then reverts to its standlight.
The Solidlights unclips but the Edelux is permanently fixed, hopefully it won't get ripped off...
Also, it's the recent version of the solidlights, the XB2, not the original which by today's standards was feeble.
I did try the two lights in series but the solidlights flickers and generally doesn't really cope, I assume the Edelux works on less current so limits it to less than the solidlights needs - in short it's either/or. With another light that's better matched to the Edelux I expect it would be possible to have a simpler system where the lights are in series and both lit at speed, and the second light is simply shorted out to get the dipped beam only.
I don't want to try the lights in series as I don't know what current the hub will cope with and I find anyway that with the solidlights on, the Edelux doesn't really add much so better not to push any boundaries, the switching is simply either/or.
Cost-wise this system's a joke, I only have all these bits cos I got them one by one, but if you already have a Schmidt and a single front light then fitting another light and a switch isn't going to be a huge cost. It's obviously for the nerdily-orientated, but I did get fed up of having to shield the front light with my hand every time an oncoming car appeared.
PS that ugly stuff on the back of the solidlights (I mean, even uglier than the solidlights itself), involves a long story - don't ask!
