Portable Light Lane
I just seen this at New Scientist site.It was 1 of 10 new designs awarded.Not on the market now but maybe later.I just thought the concept was cool.
Personal cycle lane
Cycle lanes are a good way of keeping bikes away from cars and minimising accidents, but they aren't available on every road.
Evan Gant at the Industrial Designers Society of America (IDSA) and Alex Tee of Altitude Inc in Somerville, Massachusetts, have designed a portable cycle "Light Lane" that straps to the back of a bike.
A laser projects an image of a cycle lane onto the road directly behind the cyclist to remind approaching cars to leave room.
