I think the best dynamo rear light is the B&M Topline Plus:

It puts out a red straight line behind you, rather than just a red dot like most lights do. When I'm a driver it's the most visible non-blinking light I've seen. I really like a dynamo rear light because it turns on automatically when the front light turns on, and you don't have to worry about the battery running out (a bigger issue because it's behind you and you can't see it).

Here's a listing of some other dynamo rear lights though like I said I think the topline is the best:

For the front light, I personally would have gone at least for the IQ-XS (70 lux):

They also make a brighter one the IQ-X (100lux):

The Lumotec Eyc at 50lux seems a bit weak in my experience, though how much light a person feels they need varies from person to person. It just seems kinda silly to spend $150-$250 on a wheel+dymamo, then go with a cheaper light.

I personally just paid the bike shop to do it, I don't know what your time/money ratio is, but I know that bike shops are always much better at wiring stuff onto my bike than I am.

Lastly, I'll be building up at least one more bike with a hub dynamo, this one my for my tourer, so I'm thinking of going with a hub with better slow speed functioning (I move really slow in hilly terrain with all my camping gear), and also will want to recharge my phone. Any recommendations? This bike will see some (mild) singletrack use as well, and will get handled by train personnel, any tips for particularly durable routing/runs for the wiring?

My experience with a single hub is it's the light itself that determines how well it works at lower speeds, not the hub. Admittedly I haven't used other hubs but I have switched lights. My B&M Cyo worked perfectly fine at walking speeds (less light output obviously but you're going slower so you need less) whereas my Schmidt Edelux (an expensive and supposedly high end light) worked pretty poorly at walking speeds with a lot more flickering and such.

There's a few things with using a dynamo with single track:
- Most dynamo lights are "shaped" beams like a car's low beam where it doesn't put any light "up". This may not work well for mountain biking though you can buy "round" dynamo lights as well, Supernova sells at least one.
- They can provide sufficient light for biking by yourself, but once you're biking with others it can become a lights arms race where you have trouble seeing with your light because the guy behind you has a much brighter light, and your eyes adjust to the light output of his light.

I've always been curious to try a dynamo light for mountain biking but have never quite gotten around to doing it.
