We all know the song, and we're even more familiar with the shirtless high-fives that accompanied it. However, while the locker rooms of flight school seem like quite the daunting environment, it's nothing compared to riding the streets after the bars let out. That's why Portland Design Works made the Danger Zone Tail Light. As close as it gets to having eyes in the back of your head, the Danger Zone makes you a visible part of traffic and will keep drivers off of your back. Portland Design Works' Danger Zone Tail Light lives up to the image that its name conjures. You'll feel like you're riding with tomahawk missiles and a bird-named copilot when you're around inattentive drivers. And like a fighter jet, the Danger Zone has more bells and whistles than you knew you could have, but now that you have them, you can't let them go. At the heart of the system are two 0.5, Nichia brand Japaenese Red LEDs. Together, they jam a death-ray sized beam of pure light out to the eyes of distracted drivers. The Danger Zone is powered by two AAA batteries, and is housed in a water-resistant case.The light features three strobe settings -- zZz pop, a-HA! and rock steady. We know that the names tell a visual story, but because they're so cool, we'll break them down for you. The zZz pop displays how it sounds. The output swells to a crescendo of light before going 'pop' into a dazzling array of strobing madness. a-Ha! strobes like the light bulb turning on when you're struck with a brilliant idea. Rock Steady is just a fun way to say solid beam. Remarkably, the Danger Zone can blink for around 50 hours per battery cycle, and can go for around 15 hours on steady.For easy attachment, the light comes with mounts for your seatpost and seat stays. PDW also included a backpack clip if you think that your bike is too pretty for mounting hardware.The Portland Design Works Danger Zone Tail Light is available in a 34x34x71mm size. The light also includes two AAA batteries.
Powered by two AAA batteries that go a long way. Carry two extra batteries and you can go all day and night on this. You may not even need the extra batteries. I prefer this over the USB rechargable. Actual price is about 1/4 of the listed MSRP.
