Finally located some pics of my setup. Managed somehow to loose some though. Easy to make setup. Malibu spotlight, most of the spike cut off, 12V sealed lead acid (SLA) in a fanny pack with Anderson Powerpoles as a connector. Stock 20W halogen, does good at lighting up the whole shoulder of the road, although I do want to add a narrow LED backup light.

The connector will disconnect very easily; I just drape the wire over my shoulder when riding. Someday, I'll find a suitable bag of some sort so as to hang the battery from the bike. Next up is the rear light; at the moment, it's just an old LED blinkie on the fanny pack.

Only one issue so far: my 7Ahr SLA is going kaput. Measures 10.8V unloaded, and will initially drop to 5V when plugged into my 20W halogen! It does recover to 9.8V or so. Tomorrow I'll go hunting for a replacement.
