2. Safety & Warnings

Please read all safety warnings carefully before installation or use to prevent injury or damage.

• Power Disconnection: Before installing, disassembling, or repairing this product, the vehicle power must be completely cut off. Ensure the engine and all light switches are off. Live operation is strictly prohibited to prevent electric shock and short circuits.
• Unauthorized Modification: It is prohibited to modify the product circuit, power, lighting color, or sealing structure without authorization. Such modifications will void the warranty and may cause safety hazards like short circuits and fires.
• Heat Generation: When the taillights are working, they will generate slight heat, which is normal. Do not touch high-temperature parts of the lamp body with bare hands to avoid burns. Do not place flammable, explosive, or melting objects near the lamp body.
• Child Safety: Children are prohibited from coming into contact with this product, installation tools, and wiring to prevent accidental ingestion of small parts, electric shock, or scratches from tools.
• Abnormal Conditions: If you observe abnormal conditions such as water ingress, fogging, flashing lights, non-illumination, circuit overheating, or unusual odors from the taillights, immediately turn off the vehicle power, stop using the product, and contact for after-sales maintenance. Continued use under these conditions is strictly prohibited.
• Installation Handling: During installation, avoid forcefully squeezing or colliding with the lamp body to prevent the lampshade from breaking or damaging the LED beads, which could affect normal product function.

4. Installation Instructions

Before beginning, ensure you have appropriate tools and have read the safety warnings.

Step 1: Determine the Installation Position

• Align the tail lights with the preset installation positions on both sides of the vehicle rear.
• For universal types, select a suitable installation area. For special vehicle types, directly align with the original vehicle tail light installation position.
• Ensure that key components such as the license plate, reversing radar, and reflective strips are not blocked after installation.
• Verify that the light irradiation direction is unobstructed, can be clearly identified by following vehicles, and fits the body lines for aesthetic installation.

Step 2: Fix the Tail Light Bracket

• Universal Tail Light: Align the matching mounting bracket with the preset installation position. Fix it evenly with matching screws, ensuring the bracket is firmly installed, with no looseness or skew, and closely attached to the vehicle body.
• Special Vehicle Type Tail Light: No additional mounting bracket is required. Gently pry and remove the original vehicle tail light (to avoid damaging body buckles). Replace the original vehicle tail light with this product and align it with the installation hole.
• Embed the new tail light into the bracket (or directly align with the installation hole). Adjust the angle of the tail light to ensure it is closely attached to the vehicle body, firmly installed, with no looseness, and a flat and beautiful appearance.

Step 3: Connect the Wiring Harness

1. Locate Light Control Circuit: At the rear of the vehicle, use a multimeter to accurately confirm each function line: position light positive pole, brake light positive pole, turn signal light positive pole, reverse light positive pole, and common negative pole (typically a black wire).
2. Connect Wiring Harness: Connect each function wire of the tail light wiring harness to the corresponding vehicle line one by one. The red wire corresponds to the positive pole, and the black wire corresponds to the negative pole. Tightly wrap the connection part with insulating tape to ensure a firm connection, no exposed wires, no poor contact, and to avoid short circuits.
3. Arrange Wires: Properly fix the connected wiring harness inside the vehicle body. Avoid the wiring harness being squeezed or worn, and ensure it does not affect the normal work of other vehicle components.

5. Operation & Testing

Step 4: Test and Debug

1. Turn on the vehicle power supply.
2. Test each function of the tail light in sequence:
   • Turn on the position light to confirm it is normally on.
   • Step on the brake pedal to confirm the brake light is brightly on.
   • Turn on the left and right turn signal lights to confirm they flash normally.
   • Shift into reverse gear to confirm the reverse light is normally on.
3. During the test, check that the light brightness is uniform, there is no flicker, no extinction, no abnormal heating of the line, the tail light is firmly installed, and there is no looseness or abnormal noise.
4. Once all checks pass, the tail light installation work is completely completed.

6. Maintenance & Storage

Cleaning

• Turn off the device before cleaning.
• Use a soft, lint-free cloth to wipe the surface. Do not use abrasive cleaners or solvents.

Storage

• Store in a dry place at room temperature (15°C - 35°C).
• Avoid direct sunlight or extreme temperatures.

7. Troubleshooting

If you encounter any issues, refer to the following:

• No Illumination: Check wiring connections for looseness or corrosion. Ensure vehicle power is on. Verify the correct polarity of connections.
• Flickering Lights: Check for loose connections or poor grounding. Ensure the voltage supply is stable (12V/24V).
• Water Ingress/Fogging: This indicates a potential seal failure. Discontinue use immediately and contact support.
• Overheating/Odor: Immediately turn off vehicle power. This could indicate a short circuit or electrical fault. Do not attempt to fix yourself; contact support.

For issues not listed or if troubleshooting steps do not resolve the problem, please contact customer support.
