how it is made:

what you need:
— LilyPad Arduino main board
— FTDI connector
— mini USB cable
–LilyPad power supply
— 16 LilyPad LEDs
— 2 push button switches
— a spool of 4-ply conductive thread
— a garment or a piece of fabric to work on

Both work great on their own, one for the front, the other for the back.

A combination of both could be cool.

Questions? Back lights will be covered, when carrying a backpack Necessity of lights attached/inside clothing? Better attached to the bike?
