On a road bike, a light that sits low on the bar keeps the cockpit clean, and the Lezyne Road Drive 500 does that with a slim CNC-machined aluminum body on a low-profile quarter-turn mount. A disruptive daytime flash mode makes this road bike light stand out in daylight. The body carries an IPX7 waterproof rating. What Our Gearhead(R) Experts Are Saying:"On dark evening rides, the road-optimized beam lit the pavement ahead. The be-seen optics made me easy to spot for the traffic around me."
