4. Installation (Setup)
Follow these steps carefully for proper installation. Refer to your vehicle's service manual for specific instructions on removing existing components.
- Prepare Vehicle: Turn off the vehicle's engine and disconnect the negative terminal of the battery to prevent short circuits during installation.
- Remove Old Headlight: Use T15/T20 tools (or appropriate tools for your vehicle) to remove the fixing screws of the original headlight assembly. Carefully unplug the factory wiring harness from the old headlight.
- Connect New Headlight: Match the provided adapter cable according to your vehicle model. Connect the new headlight assembly plug to the vehicle's wiring harness and ensure the buckle is securely in place.
- Secure and Test: Mount the new headlight assembly into its position. Before fully tightening, temporarily reconnect the battery and power on the vehicle to test the high beam, low beam, angel eye (DRL), and any steering functions (if applicable) to ensure they are working normally.
- Adjust and Finalize: Adjust the height and angle of the light beam for optimal visibility and to avoid dazzling oncoming traffic. Once adjusted, reinstall any decorative covers and securely reconnect the negative battery terminal.
4.1 Wiring Diagram
The headlights use a standard H4 connector for main functions and a separate wire for the running light (DRL).

Figure 4.1: Wiring diagram for the headlight plug. The standard H4 connector pins are labeled: Negative, High beam, Low beam. A separate wire is provided for the Running light. Below, the distinct beam patterns for High Beam (focused, wide) and Low Beam (cut-off, wider) are illustrated.
- H4 Connector: Typically includes pins for Negative (Ground), High Beam, and Low Beam.
- Separate Wire: Connects to the vehicle's running light or DRL circuit.
5. Operation
Once installed, your LED headlights operate like standard vehicle headlights. Use your vehicle's headlight switch to control the functions.
- Low Beam: Provides a focused, cut-off beam pattern suitable for general driving without dazzling oncoming traffic.
- High Beam: Provides a wider, more intense beam pattern for maximum visibility on unlit roads.
- Running Light (DRL): Activates when the vehicle's DRL circuit is engaged, providing enhanced daytime visibility.
6. Maintenance & Storage
6.1 Cleaning
To clean your headlights, first turn off the vehicle and ensure the lights are cool. Use a soft, lint-free cloth dampened with water or a mild automotive cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the lens.
6.2 Storage
If the headlights are removed or stored for an extended period, keep them in a dry place at room temperature (15°C - 35°C). Protect them from direct sunlight and extreme temperatures.
7. Troubleshooting
- Headlight Not Working: Check all wiring connections to ensure they are secure. Verify that the vehicle's fuses related to the headlights are intact. Ensure the negative battery terminal is properly connected.
- Flickering: Ensure all connections are tight. If flickering persists, it might indicate an issue with the vehicle's electrical system or a need for an anti-flicker harness (not included, may be required for some vehicle models).
- One Headlight Out: Check the specific wiring and connections for the non-functioning headlight. Swap the headlights (if possible) to determine if the issue is with the headlight unit or the vehicle's wiring.
