It's spring! Go biking! Everyone knows the arm signals for biking, right?

Left arm extended straight out
= Turning Left

Left arm bent upward
= Turning Right

Left arm bent downward
= Stopping

You didn't know that? Oh. Most auto-motorists don't either. Also, if you're riding at night, even if you're wearing a reflective vest, they totally can't see your arms. Conclusion: if you go biking, you're probably going to die.

Unless! Unless genius Leah Beuchley's brilliant turn signal jacket idea gets picked up and manufactured!

Leah Buechley's jacket is made with a Lilypad Arduino (that's it between the arrows), LEDs, and has wrist mounted switches for control. Hopefully someone will put this on the market soon! This jacket really could save lives. You heard about it here first!
