Okay, my turn! I have been inspired to 'roll-my-own' light system by the great information in this thread. I used an Intermatic LV505 25 watt sealed beam headlight from Home Depot (2 for $18), a Vector Pocket Power 12 SLA battery ($20 total with recharger), a 8 LED taillight from AutoZone, and a Velleman HAA40 Amber Strobe ($9). The strobe, taillight, battery and switches are housed in a cheap plastic toolbox strapped to the rear rack. The headlight is connected with a trailer connector so I can remove the box and leave the headlight on the bike. I used the mount for the front white reflector to attach the light to. The switches for the lights and strobe are accessed from the small yellows doors on the top of the box.

I want to thank all on this thread for their efforts and sharing of information.
