The ROCKBROS Q5 Smart Brake & Tail Light is a compact, durable rear light that automatically brightens when you brake. Using an in-built motion sensor, it detects deceleration and flashes a stronger brake light to alert riders and drivers behind you. It offers four main light modes—constant, breathing, SOS, and flashing—and works with brake light activation in any mode. Made from tough aluminium alloy, it mounts easily to either your saddle or seatpost and features IPX6 waterproof protection for wet-weather riding. USB-rechargeable with long battery life, it’s a reliable safety upgrade for day and night rides.
