Safe Turn

Basically, Safe Turn is a wrist-mounted indicator light thatautomatically flickers to life whenever a cyclist raises his/her arm tosignal a turn. In order to prevent the device from lighting duringnormal actions, like reaching for a water bottle or scratching the noseor ass, the device incorporates a "delayed start" feature that onlyallows the light to turn on if the user's arm has been in position formore than 200 milliseconds. If you are one of the few cyclists out there who is courteous enoughto use hand signals on the road, the Safe Turn may be a useful device.
