Using bicycles instead of cars is possibly the greenest and healthiest alternative to cars. The sad thing is not all roads are bike friendly and pedalling around town at night could be really
dangerous. Now here is a clever little gadget from Xfire called Bike Light Safety Line which could help cyclists mark their own personal space on the road.
The Xfire Bike Lane Safety Light uses two 5mW red lasers to create bike lane marks on each side of the bike and five red LEDs to increase overall visibility. This gadget uses two AAA batteries
and would cost bikers $40 each.
