Please looking for recommend on the best bike light DIY on Instructables! Answered

Hello,

Subject pretty much says all. I'm getting dizzy going through all the bike lighting projects here on Instructables :)

Could anyone recommend a good setup that is :

1) Relatively low cost
2) Easy to do
3) Bright
4) Uses standard AAA or AA type batteries (already have these and great charger)
5) Possibly shared system for headlight and flashing tail light

This is on a newer urban type bike, so I'd like something I can tie down pretty well. Been using the old hose clamp and 1 LED flashlight for a few years. It's not very good. Thanks for any pointers!
