I really enjoyed creating my own rear lights for the bike. Using a Dual 18650 Powerbank case (these are really cheap on Ebay $1.60NZ), mounting an Arduino Mini Pro in 1 of the battery spaces, opens up many Arduino Project possibilities. Using the WS2812 programmable LEDS was an obvious choice, at one stage I was riding down the street at night with rainbow colours streaming all over my bike, yep totally illegal. Back to basics, red only (I did add a red yellow startup flash loop at the beginning, couldn't resist).
