For the front, I'm using 5 and 7watt (500-900 lumen) CREE lights that use rechargeable 18650 batteries. The batteries last 1-3 hours depending on the use of high/low/flashing mode. They are mounted on Minoura and Terracycle accessory posts mounted on the front derailleur post. Right now, I have a third light mounted on my helmet - a 300 lumen CREE - for looking at things not directly in my path (street signs, around turns, at cars, etc.).

For the rear, I have a couple of cheap blinkies (which use AAA's that last over 40 hours) but am probably switching to 300 lumen CREE's (also powered by rechargeable 1860s) that I will stick red plastic "lenses" over - made from 3-D glasses I'm going to get cheaply off eBay. (I stole this idea from someone over on BROL).

As you can see, I've decided to simplify my battery/power setup.

I also use 2 flags - a large reflective safety flag and a smaller orange safety flag (on a 2nd pole).

I decided NOT to go with a dyno-powered setup because I had the batteries and recharging system AND the lights I'm using cost far less than any dynamometer light setup that I priced. Another consideration for me was there are no dyno hubs that fit my trike - a TerraTrike Cruiser - so I'd have had to go with bottle dyno's. Not all tires have sidewalls that are reinforced well enough for dyno use.
