This clever 'Light Lane' design from Alex Tee and Evan Gant of Altitude Inc projects a bike path onto roadways directly from the bicycle. The red laser boundaries are easy to see at night, and are far cheaper than the $5,000-$50,000 per mile fee Altitude cites as the installation cost of the dedicated bike lanes that adorn a portion of city streets.

The Light Lane would be a fantastic way to safeguard cyclists and make nighttime bicycling a more feasible mode of metropolitan transportation.
