Diode Dynamics 90mm switchback halo ring pair combines high-density LEDs and a phosphor coating for a clean, solid ring appearance that reads well in daylight. Each ring runs from a waterproof PWM driver offering low-, high-, and turn-signal modes; drivers default to low-priority so one input takes precedence. The pair ships with drivers, pigtails with T-taps, and mounting tabs for fitment.
