NOVSIGHT HALO Series ACC Installation Guide – Step-by-Step Tutorial

Installing the NOVSIGHT HALO Series ACC system enhances your vehicle’s lighting with customizable daytime running lights (DRLs) and synchronized main beam control. This guide provides a clear, step-by-step installation process to ensure proper functionality and safety.

🔧 Tools & Preparation

Before starting, gather the following:

NOVSIGHT HALO Series ACC wiring harness
Vehicle-specific connector cable (check compatibility)
Basic tools (wire strippers, electrical tape, multimeter)
Vehicle owner’s manual (for wiring reference)

⚠️ Safety First: Disconnect the battery negative terminal before wiring to prevent short circuits.

🔌 Step 1: Power Connections

Red wire → Connect to the positive terminal (12V power source).
Black wire → Connect to the negative terminal (ground).

✅ Verification: Use a multimeter to confirm stable power before proceeding.

🚗 Step 2: Locate Vehicle Wiring Control Center

Open the vehicle’s wiring control center (location varies; consult your manual).
Identify the daytime running light (DRL) control interface.
Use a vehicle-specific adapter for a secure connection.

📌 Pro Tip: Label wires to avoid confusion during reassembly.

⚡ Step 3: ACC Wiring Guide

Wire Color	Function	Connection Point
Yellow	Controls amber DRLs	DRL control circuit
Blue	Controls white DRLs	DRL control circuit
Green	Controls main beam	⚠️ Must connect to high beam control

Testing Each Connection

Connect the blue wire → Start the vehicle → White halo DRLs should activate.
Connect the yellow wire → Restart → Amber halo DRLs should activate.
Connect the green wire → Test high beams → Main beam should sync correctl.

🔄 System Behavior & Priority

Manual Button Control: The harness button overrides ACC settings for instant adjustments.
Automatic Mode: If no button is pressed, the halo lights sync with the vehicle’s DRLs (turn on/off with the ignition).

🚨 Troubleshooting Tips

❌ No Power?

Check fuse connections.
Verify proper grounding of the black wire.

❌ Lights Not Syncing?

Ensure the green wire is connected to high beam control, not low beam.
Recheck DRL circuit compatibility.

📌 Final Notes

Consult your vehicle manual for exact wire locations.
Secure all connections with electrical tape or heat shrink tubing.
For advanced customization, refer to NOVSIGHT’s official documentation.
