Why We Like The KTV Pro Alert Drive Tail Light

Because not every driver understands our hand signals, the KTV Pro Alert Drive Tail Light sends the message. Lezyne's Alert lights use accelerometers to measure our speed, and the LEDs inside react, changing the glow of the light and signaling to other on-road travelers. When we decelerate, the light glows solid, mimicking a car's brake light, and when we stop, the light flashes, alerting oncomers of our bike ahead.
