RiderNav RLC3 Universal Rotary Dimmer Controller Kit

One Knob. Total Control.

The universal command center for your Q5 Pro auxiliary spotlights.

Mounted within reach on your handlebar, the RiderNav RLC3 Universal Rotary Dimmer Controller Kit puts every lighting function one press, one twist, or one hold away. From instant power-on to stepless dimming with real-time visual feedback, from dual-color switching to emergency strobe, every interaction is designed to feel natural—even with gloves on, at speed, and on rough roads.

Designed to work with virtually any motorcycle, the RLC3 brings precise lighting control to riders who refuse to compromise.

Everything You Need, in One Control

The RLC3 smart wiring harness is built around a single rotary knob switch, combining an encoder dial and a dedicated auxiliary high-beam button. With these two inputs, the RLC3 delivers a complete range of lighting control:

• Power On / Off — Press the encoder knob to switch your spotlights on or off.
• Stepless Dimming — Rotate the knob to smoothly adjust brightness across the entire range, with no fixed steps or sudden jumps.
• Warning / Flash Function — Trigger an attention-grabbing flash to alert traffic ahead.
• High-Beam Control — The dedicated button provides instant auxiliary high-beam activation at the touch of a button.

By integrating multiple functions into a minimal, glove-friendly design, the RLC3 keeps your handlebars clean and operation effortless.

See Your Brightness at a Glance

The RLC3 features an intuitive color-gradient backlight indicator. As you increase brightness, the indicator LED smoothly transitions from green to blue—green for lower output and blue for maximum output. A quick glance tells you exactly where your spotlights are set, day or night, without distracting you from the road.
