5. Installation
This section provides general installation guidelines. Specific steps may vary slightly depending on your motorcycle's configuration. Professional installation is recommended if you are not comfortable with electrical work or drilling.
5.1 Preparation
- Park your motorcycle on a level surface and ensure it is stable.
- Turn off the ignition and remove the key.
- Disconnect the motorcycle's battery (negative terminal first) to prevent accidental electrical shorts.
- Identify the mounting location on the rear fender.
5.2 Mounting the Light
- Carefully position the new fender trim light on the desired location on the rear fender.
- Mark the exact spot where the wiring will pass through and where any mounting screws (if applicable) will be placed.
- Drilling Required: A hole needs to be drilled on the rear fender for the wiring to pass through. Use an appropriate drill bit size to ensure a snug fit for the wiring harness without damaging the wires. Deburr the hole edges.
- Clean the mounting surface thoroughly with an alcohol wipe to ensure optimal adhesion for the 3M tape. Allow it to dry completely.
- Peel off the backing from the 3M adhesive tape on the back of the light.
- Carefully align the light with the drilled hole and press firmly into place for at least 30 seconds to ensure a strong bond.
5.3 Wiring Connection
This product features a 'plug and play' design, simplifying the electrical connection.
- Route the wiring harness from the new light through the drilled hole to the motorcycle's existing tail light wiring.
- Connect the provided wiring harness to the motorcycle's tail light system. This typically involves connecting to the running light and brake light circuits. Refer to your motorcycle's service manual for specific wiring diagrams if needed.
- Ensure all connections are secure and properly insulated to prevent moisture ingress and short circuits.
5.4 Testing
- Reconnect the motorcycle's battery (positive terminal first, then negative).
- Turn on the ignition and test the running light function.
- Apply the brake to test the brake light function. The light should illuminate brighter when the brake is applied.
- If the lights do not function correctly, recheck all wiring connections.

6. Operation
The RUNNING PANTHER Rear Fender Trim Tail Light operates automatically with your motorcycle's electrical system.
- Running Light: When your motorcycle's ignition is on and headlights/taillights are activated, the fender trim light will illuminate at a standard brightness, acting as an additional running light to increase your visibility to other road users.
- Brake Light: When the brake lever or pedal is engaged, the fender trim light will increase in brightness, signaling to following traffic that you are slowing down or stopping.
7. Maintenance
- Cleaning: Clean the light housing with a soft, damp cloth and mild soap. Avoid abrasive cleaners or solvents that could damage the plastic or LED lens.
- Inspection: Periodically check the light for any signs of damage, loose connections, or wear. Ensure the 3M adhesive is still securely holding the light in place.
- Waterproofing: The light is designed to be waterproof. However, avoid directing high-pressure water sprays directly at the light or its wiring connections during washing.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not illuminate | Loose wiring connection, blown fuse, incorrect wiring, faulty LED. | Check all wiring connections. Inspect motorcycle fuses. Verify wiring against motorcycle's diagram. If still not working, the LED unit may be faulty. |
| Light is always bright (brake light intensity) | Incorrect wiring (running light connected to brake light circuit). | Recheck wiring connections to ensure running light and brake light circuits are correctly identified and connected. |
| Light is dim or flickers | Poor electrical connection, low voltage, damaged wiring. | Inspect connections for corrosion or looseness. Check motorcycle's battery voltage. Examine wiring for cuts or damage. |
| Light falls off or becomes loose | Improper surface cleaning during installation, adhesive failure. | Clean the surface thoroughly and reapply with new, strong automotive-grade 3M adhesive tape. Ensure firm pressure during application. |
9. User Tips
- Visibility: This light significantly enhances rear visibility. For optimal safety, ensure your motorcycle's main tail and brake lights are also in good working order.
- Trailer Compatibility: The slim profile of this light is designed to allow for the use of a trailer hitch. Always ensure proper clearance and functionality when towing.
