Harley Road Glide LED Headlight Upgrade Installation Guide

Harley Road Glide LED Headlight Upgrade Installation Guide

Dave Oberst |


The Harley-Davidson Road Glide is one of the most iconic touring motorcycles ever built—loved for its shark-nose fairing, frame-mounted stability, and unmistakable dual-headlight setup. But if you’re still running stock halogen bulbs, you’re missing out on one of the single biggest performance upgrades you can make: a high-output LED headlight system.

Whether you ride a Road Glide Standard, Special, ST, CVO, Custom Vehicle Ops model, or anything from the early EVO/Twin Cam years, upgrading to LED headlights dramatically improves your lighting power, visibility, and safety in all conditions. Riders immediately notice a wider beam spread, longer throw distance, and a clean white color that transforms nighttime visibility.

This comprehensive guide covers everything you need to know about upgrading your Harley Road Glide headlights, including: fitment by model year, the difference between pre-2015 and 2015+ fairings, best LED headlight options, installation steps, DRL wiring, CANBUS notes, troubleshooting tips, and People Also Ask–style FAQs.


Why Upgrade Your Harley Road Glide to LED Headlights?

The Road Glide is built for long-distance riding, but the stock halogen headlights were never designed for today’s highway speeds, LED-filled traffic environments, or low-visibility conditions. Here’s why thousands of Road Glide riders make the switch each year.

1. Massive Increase in Night Visibility

LED headlights produce a sharper, brighter, and wider beam pattern compared to halogen. Quality LED headlights such as Eagle Lights Road Glide LED Systems deliver:

  • Up to 6X brighter output than halogen
  • Clean white 6000K color temperature
  • Longer throw to see farther down dark roads
  • Better lighting in corners and turns
  • Improved visibility in rain, fog, and low-light conditions

2. Huge Upgrade in Safety

LED headlights help other drivers see you clearly—day or night. Many Road Glide riders report fewer close calls after upgrading, especially in heavy traffic or rural areas.

3. Long Lifespan and Lower Power Draw

Halogen bulbs burn out in ~400 hours. LED headlights last 30,000 to 50,000 hours with zero maintenance. They also draw far less power, helping preserve the charging system on longer rides.

4. Modern Custom Look

The Road Glide dual-headlight layout becomes dramatically cleaner, brighter, and more aggressive with high-output LED modules.


Road Glide Headlight Sizes & Fitment: What You Must Know

The Road Glide uses a unique dual-headlight system housed inside the shark-nose fairing. While Touring models like the Road King and Street Glide use a single 7-inch headlight, the Road Glide uses either:

  • Dual 5.75-inch headlight system (pre-2015 Road Glides)
  • Single “one-piece” LED assembly (2015 and newer)

The most important factor is the year of your bike.

Installation Guide for 1998–2013 Road Glide (Dual 5.75” Lights)

Step 1: Remove the Outer Fairing

  • Remove the windshield screws
  • Remove the outer fairing screws
  • Disconnect the turn signal harness (depending on model)

Step 2: Remove the Stock Headlights

  • Unscrew each headlight mounting ring
  • Disconnect both H4 connectors
  • Remove the stock bulbs or sealed units

Step 3: Install Both LED Headlights

  • Connect the plug-and-play H4 connectors
  • Position headlights into the headlight housings
  • Secure with mounting rings

Road Glide LED Headlight Wiring Notes

Most modern LED systems are plug-and-play, but here are some important notes for a clean installation.

2015+ Road Glide DRL Wiring

Some Road Glide LED assemblies include optional auxiliary DRL (daytime running light) wiring. These may include:

  • Halo DRL bars
  • White DRL strips
  • Amber turn signals

DRL wiring is optional but strongly recommended for maximum daytime visibility.

CANBUS Notes for 2014+ Touring Models

The Harley touring CANBUS system monitors electrical load. Quality LED systems (including all Eagle Lights Road Glide kits) include:

  • Built-in resistors
  • Anti-flicker circuitry
  • CANBUS-safe design

This ensures your lights won’t flicker, hyperflash, or throw error codes.


Common Road Glide LED Headlight Issues (and How to Fix Them)

Even with plug-and-play systems, a few common issues can occur.

1. LED Flickering on 2014+ Models

Cause: CANBUS system detecting low-load.

Fix: Use a CANBUS-stabilized LED system (all Eagle Lights assemblies include stabilization).

2. Only One Side of the Headlight Turns On (Pre-2014)

Cause: Loose H4 connector or improper grounding.

Fix: Reseat and tighten connectors.

3. DRL Bar Not Lighting Up

Cause: DRL wire not connected to accessory power.

Fix: Tap the DRL wire into switched 12V power behind the fairing.

4. Condensation Inside the Headlight

Cause: Stock rubber boot reused incorrectly.

Fix: Use the LED-compatible boot included with your kit.
