If you’ve ever been freaked out over the dangers of riding your bicycle at night, the Xfire Bike Lane Safety Light might be able to offer you a little more security. This battery-powered safety light clamps to your bike frame and projects highly visible red laser images on the ground on either side of your bike, simulating an instant bike lane that helps alert drivers to your presence. Xfire says the intense laser markers are visible over a mile away, even under headlights and streetlights.
Research suggests that lights and reflectors do have value in night cycling. A 2009 study by researchers Irene Kwan and James Mapstone for The Cochrane Collaboration finds that “Night-time cycling is two to five times more dangerous than cycling in daylight,” with “Forty per cent of cyclist fatalities occur[ing] during the hours of darkness.” One of the most important factors in collisions of all kinds is simply “the late detection of other road users.” This highlights the possible value of visibility devices such as safety lights to alert drivers earlier to the presence of the cyclist.
The shockproof and weather-resistant laser Bike Lane is made from sturdy polycarbonate. It attaches to your bicycle seat post with a universal bracket that is included. The device also includes an LED flashing taillight for extra visibility. Three included AAA batteries keep the light burning for 20 hours. Xfire, a maker of bike safety lighting systems, sells the Bike Lane Safety Light for $39.99.
