Upgrading the headlight assembly on your KTM Duke 690 to LED can enhance nighttime visibility, improve energy efficiency, and give your bike a modern look. This installation guide will walk you through each step to help you install an KTM Duke 690 LED headlight assembly with ease.

Tools and Materials Needed

• New LED headlight assembly compatible with KTM Duke 690
• Phillips and flathead screwdrivers
• Socket wrench set
• Zip ties or adhesive clips for securing wires (optional)
• Electrical tape
• Gloves and safety glasses

Step-by-Step Installation Guide

Step 1: Prepare the Bike

1. Turn off the Bike and Disconnect the Battery
   For safety, turn off the engine, remove the key, and disconnect the battery. This helps prevent accidental electrical shocks and ensures a safe installation environment.

2. Place the Bike in a Stable Position
   Position the bike on a flat surface or use a stand to keep it stable throughout the installation process.

Step 2: Remove the Existing Headlight Assembly

1. Locate the Headlight Assembly Mounting Screws
   On most KTM Duke 690 models, the headlight assembly is secured by screws along the front cowl. Use a screwdriver to carefully remove these screws.

2. Detach the Headlight from the Bracket
   After loosening the screws, gently pull the headlight assembly away from the frame. Be cautious with the wiring as you remove it.

3. Disconnect the Wiring Harness
   Locate the headlight wiring harness attached to the stock headlight assembly. Disconnect it carefully by pressing the release tab and pulling the connectors apart.

Step 3: Install the New LED Headlight Assembly

1. Attach the LED Headlight Assembly to the Wiring Harness
   Plug the new LED headlight assembly into the existing wiring harness. Ensure the connections are secure and align correctly with the power supply.

2. Secure the LED Headlight Assembly
   Once the LED headlight is connected to the wiring harness, position it in the mounting bracket and secure it in place using the mounting screws.

3. Adjust the Headlight Angle
   Before tightening the screws fully, adjust the headlight angle to ensure proper alignment for optimal road visibility. Aim the light slightly downward to avoid blinding oncoming traffic.

Step 4: Test the LED Headlight

1. Reconnect the Battery
   Reconnect the battery to restore power to the bike. Turn on the ignition to test the new LED headlight assembly.

2. Check High and Low Beams
   Switch between high and low beam settings to ensure both functions work properly. Verify that the brightness and beam pattern are satisfactory.

3. Inspect for Flickering or Connection Issues
   Make sure the light remains steady without flickering. If any flickering occurs, check all wiring connections for security.

Step 5: Secure and Organize Wiring

1. Position the Wires Properly
   If you added any extra wiring or adapters, use zip ties or adhesive clips to secure the wires away from moving parts. This prevents damage from vibration or wear over time.

2. Wrap Exposed Wires with Electrical Tape
   For added protection, wrap any exposed wires with electrical tape. This helps keep moisture out and prevents corrosion.

Step 6: Final Check

1. Test Ride
   Take a short test ride to confirm that the LED headlight assembly is secure and functioning properly. Observe the lighting on the road to ensure it meets your expectations.

2. Adjust as Needed
   After testing, make any necessary adjustments to the beam angle or tighten screws if needed.

Tips for a Successful Installation

• Use Quality Components: Make sure you choose a high-quality LED headlight that’s compatible with your Duke 690.
• Follow Local Regulations: Ensure that your new headlight assembly meets local regulations for brightness and alignment.
• Consider Waterproofing: For additional protection, consider applying a small amount of silicone sealant around the assembly edges to guard against moisture.
