If you're a cyclist, like I am, you know that things start to get a little scary this time of year because you're riding in the dark a lot more. Here's a brilliant invention -- the Xfire Safey Light. It's a battery-powered device that clamps to the post under your bike seat and uses lasers to project bright red lines ont he ground on either side fo your bike, simulating an instant bike lane that lets drivers know you're there.
It costs $39.99, which seems prety reasonable of you do a lot of riding int he dark around here, because as we cyclists know, drivers in the Nrothwest aren't all that alert even in broad dayilight. Here's some dramatic video of the Xfire Safety Light in action:
