4. Package Contents
Each package includes:
- 2 Pair (4 units) BSK Universal SMD LED Turn Signal Lights
5. Installation Guide
These turn signals are designed for easy installation, but professional installation is recommended if you are unfamiliar with motorcycle electrical systems. No specific instruction manual is included with the product, but general wiring guidelines are provided below.
Wiring Connections:
- Green Wire: Connect to Negative (-)
- Orange Wire: Connect to Left Turn Signal (+)
- Blue Wire: Connect to Right Turn Signal (+)
Ensure all connections are secure and insulated to prevent short circuits. For optimal performance and to prevent hyper-flashing (rapid blinking), an electronic LED flasher relay may be required, especially if replacing incandescent bulbs.
General Installation Steps:
- Disconnect the motorcycle's battery to prevent electrical hazards.
- Remove existing turn signals (if applicable).
- Mount the new BSK LED turn signals using the 10mm bolt. Ensure they are securely fastened.
- Connect the wires according to the wiring diagram above.
- Reconnect the battery and test the turn signals.

6. Operating Instructions
Once properly installed, the BSK Universal SMD LED Turn Signal Lights operate like standard motorcycle turn signals. Activate your motorcycle's turn signal switch to engage the lights. The SMD LEDs will illuminate brightly, providing clear indication to other road users.

7. Maintenance
The BSK LED Turn Signal Lights require minimal maintenance. Due to their waterproof and dustproof design, they are built to withstand various environmental conditions.
- Cleaning: Periodically wipe the lenses with a soft, damp cloth to remove dirt and debris. Avoid abrasive cleaners that could scratch the lens.
- Inspection: Regularly check the wiring connections for any signs of wear, corrosion, or looseness. Ensure the mounting bolts remain tight.
- Damage: If the housing or lens becomes damaged, consider replacing the unit to maintain optimal visibility and weather resistance.
8. Troubleshooting
If you encounter issues with your BSK LED Turn Signal Lights, refer to the following common problems and solutions:
- Lights not illuminating:
- Check all wiring connections for proper contact and ensure they are not loose or corroded.
- Verify that the motorcycle's power supply (12V DC) is reaching the turn signals.
- Inspect the motorcycle's fuse box for any blown fuses related to the turn signal circuit.
- Lights blinking too fast (hyper-flashing):
- This is common when replacing incandescent bulbs with LED lights due to lower power draw. An electronic LED flasher relay is typically required to correct the blink rate.
- Alternatively, load resistors can be installed in parallel with each LED turn signal, but a flasher relay is generally preferred for simplicity and efficiency.
- Lights blinking too slow or not at all:
- Ensure the correct flasher relay is installed. If an LED flasher relay is already in place, verify it is functioning correctly.
- Check for poor ground connections.
