Cheap side lighting hack

Problem: Bikes are not very visible from the side at dark/dusk
Solution: Blinky light watter bottle.

I had a co worker tell me the other day how difficult it is to see my bicycle from the side in the dark or low light. I thought of putting little blinky lights aimed to the side, but that seemed like an odd solution.

Then thought – what about a glowing water bottle?

I hung a little LED blinky light from my water bottle cap, and voila, instant 360 degree strobe for my bike!

Light hung inside bottle cap (using twist tie);
