1nterceptor, thank you so much! I have been unable to find that video, but it saved me when my cheap freebie bottle generator failed on me in the middle of a trip.
I highly recommend the innertube option shown in that video, although it is painfully slow to watch. It literally took me all of 60 seconds (or less?) to whip out my flashlight (I carry one in my purse at all times to pretrip schoolbuses) and pocket knife and create an extremely durable and sturdy attachment for my flashlight. The thing is easily removeable without being loose or susceptible to vibrations, and it is easy to adjust to point the flashlight where you need it. I don't even think it looks ugly at all since its so small, where a hose clamp just seems incredibly conspicuous to me. The best part- it's free!
I really enjoyed my generator lights while I had them, though.
