Diode Dynamics 140mm switchback halo ring pair features high-density LEDs with a durable phosphor coating for a consistent, solid appearance and daytime visibility. The rings include waterproof PWM drivers that offer low-power, high-power, and turn-signal modes; units ship with low-priority drivers by default so one input will dim when both are active. Integrated tabs ease mounting and the kit includes wiring and drivers.
