The DialDim Lighting Controller offers intuitive control of two sets of 3-wire auxiliary lights using a single, color-coded halo dimming switch. The blue halo manages one light set, the green halo the other—just double-click to switch between them. Easily adjust brightness and power with real-time visual feedback.

Integrated with high beam, turn signal, and horn inputs, it enables smart features like canceling lights with turn signals, flashing them as indicators, or strobing with the horn. The multicolor halo also shows light intensity, alerts you to blown fuses, and lets you reset them instantly. Plus, it acts as a battery monitor, flashing status at startup and shutting lights off if voltage drops too low. Waterproof construction ensures reliable performance in any conditions.

Features

• Independently control two sets of lights for ON/OFF and brightness using the single DialDim Switch
• Blue halo controls light set one, green halo controls light set two; double click to switch between them
• Auxiliary lights switch from dim to full brightness automatically with the high beam switch
• Stealth Mode keeps lights off during normal driving, but jumps to full intensity with high beam, horn, or turn signal
• Main lights cancel with turn signal to avoid overpowering the factory signal
• Amber lights flash in sync with your vehicle’s turn signals
• Auxiliary lights strobe when you sound the horn
• Both circuits are electronically fused and fuse settings can be adjusted via the switch
• Halo glows red when a fuse is tripped
• On startup, switch halo flashes green for healthy battery or red for low battery (below 11.8v)
• Lights won’t power on if battery voltage drops below 10.8v; switch flashes red LEDs as a warning
