One of the problems with most tail lights for bicycles is that they frequently get stolen by bad guys. Since attaching a piranha fish tank to your bike seat is outlawed in 49 of the 50 states (stay gutsy, Maine!), the next best way to avoid theft and let cars see you at night is the LightSKIN integrated bike post seat lights. The LEDs are easily embedded inside the seatpost, making them perfect for alerting nighttime drivers of your presence, while staying off the radar of crooks.
