That was when we lived in Olympia, WA. Those 2 on the bar are Vista Light Halogens, a 10 Watt + a 15 Watt. At 1st, I had only the 10W, powered by a used, re-chargeable "Lite Stick" battery I got from Bill Stevenson. Lite Stick hung under the TT. When that died, I added the 15W and ran both off it's 6 volt SLA hung in a cloth pouch at the TT/ST junction. The 6 volt SLA would only last for 1 rainy season. Each Fall I replaced it.

Lower light is a LumoTec Halogen powered by a swap meet, Sturmey Archer DynoHub. Corey Thompson built it into a Torelli Master rim for me. I ran the LumoTec only on country roads, turned on 1 or both the Vista Lights as needed along my commute. Still have all 3 lights, but only using the Lumotec on my Torelli at present. The final system worked quite well, and wasn't too expensive. Don

edit: found a pic of the Lite Stick but the 10 W light is hidden behind the old SA light I ran when 1st added the DynoHub. That old school SA headlight was pretty dim. Lumotec was a big improvement.
