Most of my riding is where there's street lights but lately been riding on roads where there's none.

Back is a Knog Blinder 4V (solid or flash) and on the back of my helmet a Niterider Cherry bomb flashing.

Front is a Knog Blinder 4 in flashing mode and a generic eBay cree with the battery pack under the stem. The cree runs in medium when there's street lights and high where there's none.
Commute backpack and some of my shirts/jackets have reflective patches.
During the day I'll normally run one rear flashing (either one) and the front Knog flashing FWIW.
Same setup easily moved to the Ridley X-Bow when I ride that
