ARG STALLED and waiting for a charger. The seller just e-mailed and said he can't send it because it's defective...

I tend to push equipment to the limits (so it's worth muddling around for the best solution). Basically everything had to be done twice. But outside of wiring everything is new and I'm learning so much.

Stuff that failed:
A. First, I tried to set up a system like what Raymond's. But for our steep terrain and on a road bike, the 5lb weight would have been too tippy.

B. Switching to the 16.8V battery prevented adequate waterproofing
A baggie would have been OK, but I couldn't make a stable enough switch either. Water is a problem in Seattle. The LBS just drained the rear hub on my bike and said..."you ride alot in the rain?"

C. The wiring had to changed from the 14G, to 4-Wire trailer with plugs to swap between battery and recharger.

The front headlight is just the first hurdle. What I really need are front and rear turn signals (both on one curcuit). 'cause at the end of a long decent, I have to signal a left turn AND brake. Oncoming traffic seems to need about a full 10 seconds of signaling (to distract 'em from their cell phones etc).
