Blink Steady Bike Light
No need to ruin the sleek design of your bike by some Velcro-secured plastic monstrosity of a light. The Blink Steady Bike Light ($125) is more than capable of keeping you safe while adding to the aesthetic of your cycle. Machined from solid aluminum in Brooklyn, this smart light secures to your seatpost, making theft highly unlikely, and sports an internal accelerometer that turns the LEDs on when you're riding and off when you're not, and makes the choice between a blinking or steady indicator as easy as flipping the unit over. A photosensor senses when it's dark enough to need the light, so you're not burning through unnecessary batteries during the daytime, making this one of the smartest accessories you can bolt on to your bike.
