The Cyo is good; I have a D-Lumotec Oval, which was recommended to me at a German shop after I told them it would be going on a bike with cantilever brakes. It's got an LED (not as bright as the newer Cyo's), standlight, a nighttime-sensing circuit and an off switch.

I paired it with a B&M Selectra, which has one main LED, two side LEDs, and a standlight. If your Tikit doesn't have a rack, I'd see about getting a Seculite Plus and mounting it somewhat like Peter White posted at his site.

The lowest-profile lighting, especially the taillight, you can probably get are the Supernova lights. They'll cost a bunch more, but you'll get performance to match.
