I've been looking for low-cost solutions for lighting so that I can see my way down unlit sections of the MUP now that it'll be getting dark sooner. After much reading and searching on the electronics forum, here's what I think I'm gonna do.

The Terralux 220 lumen flashlight (http://www.terraluxcorp.com/index-retail.htm#3), available on eBay for less than $30 including shipping. Runs on AAs, too, which will make life easier. It doesn't have a flashing mode, but it'll be my "see where I'm going light" go along with the Planet Bike Beamer 1 "be seen" light anyway.

For mounting, the solution presented in this youtube video http://www.youtube.com/watch?v=HrfZhEzjWwg seems just brilliant!!! And it's free assuming you've got an old tube laying around like I do. And it doesn't look half bad either. Better than some other DIY suggestions I've seen...

Seems like the best way to get 200+ lumens for less than $30. The Terralux has gotten some very good reviews from BFers and avoids the issues of quality concerns and shipping time issues that seem somewhat common with Deal Extreme.
