Installation Guide
This section outlines the general steps for installing the YIJINSHENG DRL Kit. Specific vehicle requirements may vary.
- Plan Mounting Location: Identify a suitable, flat surface on your vehicle's front bumper or grille area for mounting the DRLs. Ensure the location allows for optimal light projection and does not obstruct other vehicle components or airflow. Consider the dimensions of the lights (10 x 1.18 x 0.86 inches) when selecting a spot.
- Prepare for Installation:
- Turn off the vehicle's engine and remove the key from the ignition.
- Disconnect the negative terminal of the vehicle's battery to prevent electrical hazards.
- Clean the chosen mounting surface thoroughly.
- Attach Mounting Brackets: Secure the provided mounting brackets to the back of each DRL unit using the included screws.

- Mount DRL Units: Position the DRL units with their attached brackets onto the chosen location. Mark the drilling points for the mounting screws. Drill pilot holes if necessary, then securely fasten the DRLs to the vehicle using the provided screws. Ensure they are firmly attached and aligned.
- Wiring Connections:
- Connect the red wire from each DRL unit to a positive (+) 12V power source that is activated when the vehicle is running (e.g., an accessory fuse, ignition wire, or a dedicated DRL module if using one).
- Connect the black wire from each DRL unit to a reliable ground (-) point on the vehicle chassis.
- Ensure all connections are tight and insulated with electrical tape or heat shrink tubing to protect against moisture and corrosion.
- Test Functionality: Reconnect the vehicle's battery. Turn on the ignition and verify that the DRLs illuminate correctly. Check for any flickering or improper operation.
- Final Adjustments: Adjust the angle of the lights if necessary to ensure optimal visibility without blinding oncoming traffic.

Operation
Once properly installed and wired, the YIJINSHENG DRLs are designed for automatic operation:
- The lights will typically turn on automatically when the vehicle's ignition is switched to the "ON" position or when the engine is running, depending on how they are wired to the 12V power source.
- They are intended to provide additional visibility during daylight hours.
- The DRLs are not designed to replace headlights or fog lights for nighttime driving or adverse weather conditions.

Maintenance
The YIJINSHENG DRLs require minimal maintenance due to their durable construction and long-lasting LEDs.
- Cleaning: Periodically clean the lens of the DRLs with a soft cloth and mild soap and water to remove dirt and debris. Avoid abrasive cleaners that could scratch the lens.
- Inspection: Regularly inspect the mounting brackets and wiring connections to ensure they remain secure and free from corrosion or damage.
- Damage: If any damage to the housing or lens occurs, consider replacing the unit to maintain optimal performance and safety.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power supply, loose wiring, blown fuse, incorrect wiring. | Check all wiring connections for tightness. Verify 12V power at the red wire and a good ground at the black wire. Check the vehicle's fuse box for any blown fuses related to the power source. Ensure the battery is connected. |
| Lights flicker or are dim. | Poor electrical connection, insufficient power, damaged unit. | Inspect wiring for loose connections or corrosion. Ensure the power source provides stable 12V. If one unit flickers, it may be damaged and require replacement. |
| Moisture inside the lens. | Seal compromise, extreme temperature changes. | Small amounts of condensation may dissipate. If persistent or significant, inspect the unit for cracks or seal damage. Ensure wiring entry points are sealed. |
| Lights become loose. | Improper mounting, vibrations. | Re-tighten mounting screws. Consider adding thread-locking compound or additional securing methods if vibrations are severe. |
