Wow! I just finished reading ALL of the past posts on this thread!!!
I was waffling about getting a Nite Hawk Dual Pro lighting system... but I think I'll be going home-brewed instead.

I'm eagerly awaiting delivery on a new F5 Enduro by Rans bicycles. It is a short wheelbase recumbent.
My commuting time will vary as I move around the country very frequently. Currently, I'm looking at probably an hour to an hour and a half of lamp time for commuting.

Because I'm going recumbent, I don't think that a standard bike light system's wires will reach from my handlebars to my bottle cage or to my mid-ship rack.

I'm thinking of going with the opitronic driving lights, a 20w Phillips high efficiency bulb for regular riding, a beehive red LED in back and the Pocket Power 12 Volt DC, 6 amp hour, Portable Power Supply.

Some questions...
For the people using the Pocket Power 12volt Portable Power Supply, how has it faired over time? Any problems? Still love it? It says that it's 4lbs... but that seems a little light for everything it has. How much does the full kit weigh?

DCCommuter, you made a reference about switching from 2-10w headlights to a 20w halogen bulb and an LED bulb. How is the new combination working for you?

I'm trying to find a beehive rear LED light. Any links? How much amps does it draw?
