Fed up with seeing friends getting clipped by cars, the designers at Altitude combined two things we love — bikes and lasers — to create an instant bike lane and make nighttime cycling a whole lot safer.

Their bike-mounted gadget, called LightLane, beams two bright red lines and the universal symbol for cyclist on the pavement, neatly delineating a bike lane to remind motorists to yield a little space. It should make everyone feel a little more comfort on the road.
