Upgrading your motorcycle with LED lighting is one of the easiest ways to improve visibility, safety, and style — all in a single afternoon. But to get the most out of your upgrade, it’s crucial to wire and mount your lights properly.
This complete 2025 guide explains how to install LED lights on a motorcycle step-by-step, including wiring, fuses, power options, and safety tips — whether you’re adding accent lights, underglow kits, or full lighting systems.
💡 Quick Answer: Use a Fused 12V Power Source and a Switch or Remote Controller
Most motorcycle LED lighting kits — including Eagle Lights accent and underglow systems — run directly off your 12V battery. Use an inline fuse, proper grounding, and a switch or wireless controller for safe, clean installation.
In short:
Battery → Fuse → Controller/Switch → LED Lights → Ground
That’s the foundation of every safe LED wiring setup.
🧰 Tools and Materials You’ll Need
-
LED light kit (single-color or RGB multicolor)
-
Inline fuse holder and 5–10 amp fuse
-
Ring terminal connectors
-
Wire strippers and crimpers
-
Electrical tape or heat shrink tubing
-
Zip ties or cable clips
-
Multimeter (for checking voltage)
-
Optional: 16–18 gauge extension wire
-
Optional: remote control or Bluetooth controller
Pro Tip: Most Eagle Lights LED accent kits come with pre-fused harnesses, controllers, and waterproof connectors — so you can skip the complicated wiring.
🏍️ Step 1: Plan Your Layout
Before you start, decide where to place each light strip or pod. Popular mounting spots include:
-
Under the gas tank or frame rails
-
Around the engine bay
-
Under the rear fender or seat
-
Inside wheel wells
-
Along footboards or fairings
Map out your layout using painter’s tape so you know where each strip will go before sticking anything permanently.
Pro Tip: Avoid placing lights too close to the exhaust, moving parts, or suspension components. Heat and vibration can damage LED strips over time.
⚙️ Step 2: Clean and Prep the Surface
LED strips adhere best to clean, smooth surfaces.
-
Wipe each mounting area with rubbing alcohol or degreaser.
-
Let surfaces dry completely.
-
Test-fit each strip or pod before removing adhesive backing.
If you’re using Eagle Lights waterproof LED kits, you’ll notice strong 3M industrial-grade backing — once it’s in place, it’s not going anywhere.
🔋 Step 3: Connect to a 12V Power Source
Your LED lights need a consistent 12V power supply. You have two main options:
Option 1: Connect Directly to the Battery
-
Connect the positive (red) wire from your LED kit to the battery’s positive terminal using an inline fuse (5–10 amps).
-
Connect the negative (black) wire to the negative terminal or frame ground.
-
Run wiring neatly along the frame using zip ties.
This setup provides steady power even when the ignition is off (use a switch or remote to control power).
Option 2: Tap Into a Switched Circuit
If you want the LEDs to turn off automatically when the ignition is off:
-
Use a circuit that only receives power when the key is on (such as the headlight or accessory fuse).
-
Use a fuse tap connector for a safe, non-invasive connection.
-
Still include an inline fuse for extra protection.
🪛 Step 4: Install the Inline Fuse and Controller
Always use an inline fuse between your LED lights and the battery. This prevents electrical shorts and protects your motorcycle’s wiring.
-
Cut the positive power wire near the battery.
-
Insert the inline fuse holder between the battery and the LED controller.
-
Insert a 5–10 amp fuse (as recommended by your LED kit).
If your lights come with a Bluetooth or wireless controller:
-
Mount it under the seat or near the battery (away from high heat).
-
Connect the controller’s red wire to your fused power source.
-
Connect the black wire to ground.
With Eagle Lights remote-controlled kits, the controller is waterproof and pre-wired — just connect to the battery and you’re ready to ride.
🧩 Step 5: Mount Your LED Strips or Pods
Once your wiring is ready, begin installing your LED lights:
-
Peel the adhesive backing and carefully place each strip.
-
Press firmly for 30–60 seconds to ensure a tight bond.
-
Secure loose wires with zip ties or clips.
-
Connect all strips or pods to the controller harness.
Pro Tip: Leave a little slack in each wire to account for vibration or frame movement while riding.
⚡ Step 6: Ground the LED System Properly
Proper grounding ensures consistent brightness and prevents flickering.
-
Connect your LED ground wire to a bare metal surface on the frame using a ring terminal.
-
Avoid painted or powder-coated areas — remove a small bit of coating if needed.
-
Secure tightly with a screw or existing ground bolt.
A clean ground is critical for long-term LED performance.
🔧 Step 7: Test Before Final Assembly
Before reassembling panels or securing every wire:
-
Turn on the ignition (or activate your controller).
-
Test all lights for brightness, color, and uniform function.
-
Check that running and brake lights (if integrated) work properly.
If you see flickering, dim output, or no response:
-
Double-check your ground connection.
-
Ensure the fuse is seated properly.
-
Verify polarity (positive and negative aren’t reversed).
Once you confirm everything works, finish securing your wires and panels.
🌧️ Step 8: Waterproof and Protect Your Wiring
Motorcycles face constant exposure to the elements, so make sure your wiring is sealed and safe:
-
Wrap exposed connectors with electrical tape or heat shrink tubing.
-
Route wires away from hot exhaust pipes or sharp edges.
-
Use waterproof connectors for all joints.
Eagle Lights LED kits are IP68 waterproof, vibration-resistant, and built for every weather condition — perfect for year-round riding.
🧠 Step 9: Safety and Legal Tips
LED accent and underglow lighting laws vary by state. To stay legal:
-
Avoid using red or blue lights on the front of your bike.
-
Do not use flashing or strobing effects on public roads.
-
Use accent lights primarily when parked or in shows, unless local laws allow while riding.
Pro Tip: Use amber, white, or green LEDs for maximum visibility without legal concerns.
🏁 Step 10: Maintain and Enjoy Your New Lighting System
LEDs require almost no maintenance — just check your wiring occasionally for wear or corrosion.
To keep your lights looking and performing their best:
-
Clean regularly with a soft microfiber cloth.
-
Avoid high-pressure water directly on connectors.
-
Keep your controller firmware updated (for Bluetooth kits).
Now you can enjoy a brighter, safer, and more custom-looking motorcycle every time you ride.
