Another "lighting" question.
 

I recently found a well kept Dunelt for my husband. My old and now crashed (while avoiding contact with a car which failed to yield) Sprite came to me with a Dynohub and lighting system. The Sprite wheels, not damaged in the altercation, are larger and I don't think there will be enough clearance to use them on the Dunelt. Is it possible to connect the SA front and rear lights from the Sprite to a bottle generator for use on my husband's bike?

yes if it is. what is the difference in wheelsize?

1 inch.

Or you could lace the dyno hub into a 26" wheel for the Dunelt. Yes the lights will work with a bottle generator, however you will need to swap the bulbs out for a higher wattage. The GH6 hub dyno puts out about 1.8 watts a typical bottle generator about 3 watts. Need a 2.4watt head light bulb and a .6 watt tail light bulb.

Aaron, thanks for the bulb advice. I'll add wheel building to my bucket list!

Well just swap wheels and find out if they'll fit? It should only take a minute at most to see if it will work or not. My personal experience has been that most of these cheaper bikes with 26 x 1 3/8" tires have more than enough clearance for 27" wheels.
