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.
