Figure 4.3: Wiring Diagram for Senlo X1plus LED Spotlights.
- Connect to Lights: Connect the flashing harness wire to the two Senlo X1plus lights.
- Connect to Battery: Connect the red power cord (with 20A fuse) to the Car Battery's DC12V+ Positive pole. Connect the black wire to the Negative pole.
- Blue Wire Connection: Connect the blue wire to the "Car Horn" DC12V+ Positive pole.
- Red Wire Connection: Connect the red wire to Car ACC/DC12V+ Positive pole.
- Waterproof Connector: Connect to A1/A3 Switches, using switches to control your lights.
Wiring Notes:
- The white wire is for the low beam.
- The yellow wire is for the high beam.
- The red wire, when connected, enables both low and high beams to be bright at the same time. If you do not need both beams simultaneously, you do not need to connect the red line.
- Ensure all connections are secure and waterproof.
Optional Flashing Effect: If you desire a flashing effect, a specialized flashing harness wire is required and may need to be purchased separately. Please contact customer service for details.

6. Maintenance
To ensure the longevity and optimal performance of your Senlo X1plus LED Spotlights, follow these simple maintenance guidelines:
- Cleaning: Regularly clean the lens and housing with a soft, damp cloth to remove dirt and debris. Avoid abrasive cleaners that could scratch the lens.
- Inspection: Periodically check the mounting brackets and wiring connections for any signs of looseness, corrosion, or damage. Tighten any loose fasteners and repair or replace damaged wiring as needed.
- Waterproofing: The lights are IP68 rated for waterproofing. While designed to withstand harsh environments, avoid directing high-pressure water jets directly at the light housing during cleaning.
- Heat Dissipation: Ensure that the cooling fins on the light housing are free from obstructions to allow for proper heat dissipation.

- Inspect the fuse in the red power cord (20A fuse) and replace if blown.
- Ensure the switch is functioning correctly.
- One Light Not Working:
- Check the individual wiring connections for the non-functioning light and its driver.
- Swap the driver with the working light's driver to determine if the issue is with the light or the driver.
- Incorrect Light Mode:
- Review the wiring for the white, yellow, and red wires to ensure they are connected as desired for low beam, high beam, or combined modes.
- Ensure the switch is correctly configured for mode selection.
- Flickering Lights:
