Benefits of LED Headlights

Before diving into the installation process, it’s important to understand why you might want to upgrade to LED headlights:

Enhanced Visibility:

LEDs produce a brighter and whiter light, improving nighttime visibility and making it easier to spot obstacles.


LED headlights last significantly longer than halogen bulbs, often up to 50,000 hours.

Energy Efficiency:

LEDs consume less power, which can reduce the load on your bike's electrical system.


LED headlights are more resistant to vibrations and shock, making them ideal for motorcycle use.

Tools and Materials Needed

To install an LED headlight on your Harley Davidson, you will need the following tools and materials:

- LED headlight kit compatible with your Harley model
- Screwdrivers (Phillips and flathead)
- Allen wrenches
- Electrical tape
- Clean cloth or gloves
- Service manual (optional but helpful)

Step-by-Step Installation Guide

Step 1: Preparation

Ensure Safety:

Park your motorcycle on a flat surface and use a bike stand if available. Turn off the engine and disconnect the battery to prevent any electrical issues.

Read the Manual:

Review the LED headlight kit manual and your Harley’s service manual to familiarize yourself with the components and installation steps.

Step 2: Remove the Existing Headlight

Access the Headlight Housing:

Depending on your Harley model, you may need to remove the fairing or other components to access the headlight housing. Use the appropriate tools to carefully remove these parts.

Unscrew the Headlight:

Locate the screws or bolts securing the headlight in place. Typically, there will be screws around the headlight bezel. Use the appropriate screwdriver to remove these.

Disconnect the Wiring:

Once the headlight is free, gently pull it out and disconnect the wiring harness. Take note of the wiring configuration for reassembly.

Step 3: Install the LED Headlight

Prepare the LED Headlight:

Unbox the new LED headlight. If your kit includes an adapter or mounting bracket, attach these to the headlight as instructed.

Connect the Wiring:

Match the wiring harness from your bike to the connectors on the LED headlight. 

Secure the Headlight:

Carefully place the LED headlight into the housing. Align it properly and secure it using the screws or bolts you previously removed. Ensure it is firmly in place to prevent any vibrations during rides.

Step 4: Test and Adjust

Reconnect the Battery:

Once the headlight is securely installed, reconnect the battery and turn on the ignition.

Test the Headlight:

Switch on the headlight to ensure it’s functioning correctly. Check both low and high beams for proper operation.

Adjust the Beam:

If necessary, adjust the headlight beam angle to ensure it illuminates the road correctly without blinding oncoming traffic. Most headlights have adjustment screws for this purpose.

Step 5: Reassemble and Final Checks

Reattach Components:

If you removed any fairings or other parts, reattach them now. Ensure all screws and bolts are tightened properly.

Final Inspection:

Do a final inspection to make sure everything is securely in place and there are no loose wires or components.

Clean Up:

Use a clean cloth or gloves to wipe down the headlight and surrounding areas, removing any fingerprints or smudges.
