The MotoGlo Motorcycle Helmet Safety Light provides increased visibility of the rider by adding running light, brake light, and turn signal indicators to the back of the driver's helmet. It uses wireless technology between the mounted transmitter and the MotoGlo helmet device. The company says it attaches easily to any ¾ or full face helmet with 3M adhesive. Some descriptions say there are models for full and half helmets, and other descriptions says full and ¾ helmet. Frankly, I'm afraid don't know the difference, but check before ordering. The rechargeable battery provides a full 12 hours of lighting on a single charge and be recharged in about an hour with the included USB charging cable. Turn signals flash amber, red brake lights pulse twice and then stay on steady. Running lights can be turned off, on steady, or flash. The spokesperson at the booth said the included transmitter module must be “hard wired” to motorcycle, which is a 15 minute operation. (Yeah, I'd figure on more than that.) The module may be paired to support 2 helmets. That way if you have a rider with a MotoGlo helmet, the rear helmet can light. Prices range from about $79.00 to $99.00.
