The Azur Ursa 550 / Smart Brake 150 Lightset is a feature-packed front and rear lighting combination engineered for commuters and everyday riders who want serious visibility and intelligent safety technology in a straightforward, easy-to-use package. The Ursa 550 front light pumps out a powerful 550-lumen beam through five versatile modes — including a Pulse Flash that overlaps a pulsating flash over a steady beam for maximum daytime attention — all housed in a durable polymer body with side visibility windows for enhanced lateral safety. At the rear, the Smart Brake 150 uses advanced 50-chip COB (Chip On Board) LED technology to deliver a brighter, more efficient light than standard LED designs, with built-in deceleration detection that automatically increases brightness when it senses you slowing down — just like a car brake light. Both lights are USB-C rechargeable, IPX4 water resistant, and feature tool-free quick-release brackets for effortless mounting and removal.
