Introduction: Brighten Up Your Setup with Custom Lighting
Your Corsair Scimitar isn’t just a gaming mouse—it’s a canvas for creativity. With its 17-zone RGB lighting, you can transform your desk into a dynamic space that reflects your personality. But how do you change those lighting effects? That’s exactly what this guide covers.
In this step-by-step tutorial, you’ll learn how to use iCUE software (the modern version of Corsair Utility Engine) to customize every aspect of your Scimitar’s lighting. Whether you want a calm blue glow during work hours or pulsating red during gameplay, we’ve got you covered. By the end, you’ll know how to navigate iCUE, apply effects, adjust brightness, and even create custom profiles.
Let’s get started—your perfectly lit Scimitar awaits!
What Is iCUE and Why Do You Need It?
If you’re reading this, chances are you already own a Corsair Scimitar. Congrats! But here’s the catch: you can’t change its lighting without iCUE software. iCUE stands for “Corsair iCUE Software” and is the official program used to control Corsair peripherals like keyboards, headsets, and yes—mice.

iCUE replaced the older “Corsair Utility Engine” around 2018. If your mouse came out before that, you might still see references to CUE in old forums or videos. Just know that today, all new Corsair gear uses iCUE. So, if you’re trying to change Scimitar lighting effects, downloading iCUE is your first move.
iCUE also lets you sync lighting across multiple Corsair devices—so if you have a keyboard and headset too, everything can glow in harmony. Plus, it supports macros, performance tuning, and firmware updates. Think of iCUE as the command center for your entire Corsair ecosystem.
Step 1: Download and Install iCUE Software
Visit Corsair’s Official Website
Go to corsair.com and click on “Support” in the top menu. Then select “Downloads” and search for “iCUE.” Make sure you’re on the legitimate site—avoid third-party download links, as they may bundle unwanted software or malware.
Download the Latest Version
Click the green “Download Now” button next to iCUE. The installer will begin automatically. Save it to your desktop or Downloads folder for easy access.
Run the Installer
Double-click the downloaded file (usually named something like “icue-install.exe”). Allow the program to make changes to your device when prompted by Windows. Follow the on-screen instructions—accept the license agreement, choose installation location (default is fine), and click “Install.”
Restart Your Computer (Optional but Recommended)
While not always necessary, restarting ensures iCUE integrates properly with your system. After reboot, launch iCUE from your Start menu or desktop shortcut.
Step 2: Connect Your Corsair Scimitar
Plug your Scimitar into an available USB port on your PC. Use the original cable if possible—some users report better recognition with high-quality cables. Avoid USB hubs; plug directly into your motherboard’s ports for best results.
Wait about 10–15 seconds after connecting. iCUE should detect the mouse automatically. A small icon of your Scimitar will appear in the left sidebar under “Devices.” If it doesn’t show up immediately, try unplugging and reconnecting the mouse.
Step 3: Navigate the iCUE Interface
Once iCUE opens, you’ll see a clean, intuitive dashboard. On the left, you’ll find a list of connected Corsair devices. Click on your Scimitar to open its control panel.
The main screen displays three tabs at the top:
- Lighting: Where you’ll spend most of your time changing effects.
- Performance: Adjust DPI, polling rate, and button assignments.
- Profiles: Save and manage different configurations.
For now, focus on the Lighting tab. This is where all the magic happens.
Step 4: Access the Lighting Settings
With your Scimitar selected in iCUE, click the Lighting tab. You’ll see a visual representation of your mouse with labeled zones. The Scimitan has 17 individually addressable LEDs grouped into zones like:
- Logo (center)
- Scroll wheel
- Side buttons (left and right)
- Back edge (bottom strip)
Each zone can be controlled separately or set to follow global effects. Note: Unlike full-keyboard RGB, the Scimitan doesn’t support per-button color changes—only zone-based lighting.
Step 5: Choose a Lighting Effect
Below the mouse preview, you’ll see a dropdown menu labeled “Effect Type.” Click it to reveal dozens of options. Popular choices include:
- Static: Solid color across all zones.
- Gradient: Smooth transition between two or more colors.
- Wave: Color flows from one side to the other like a ripple.
- Reactive: Lights up when you move the mouse (great for gaming).
- Breathe: Gentle pulsing effect.
- Rainbow: Full spectrum cycling continuously.
Try selecting “Rainbow” first—it looks awesome and shows off your Scimitan’s capabilities. Then experiment with others to find your favorite.
Step 6: Customize Colors and Speed
After picking an effect, refine it using the sliders and color pickers below. Here’s what each controls:
- Color: Click the swatch to choose primary and secondary hues (for gradients/waves).
- Brightness: Drag the slider to dim or brighten the lights. Lower brightness saves power and reduces eye strain.
- Speed: Adjust how fast the effect cycles. Slower = calmer; faster = more energetic.
For example, set “Breathe” to blue at 50% brightness with a slow speed for a relaxing ambiance. Or go full throttle with “Wave” in red at 100% brightness and max speed for intense gaming vibes.
Step 7: Apply and Test Your Changes
Once satisfied, click the Apply button at the bottom-right corner. Your Scimitan should instantly reflect the new lighting effect. Give it a test—move the mouse around, click buttons, scroll the wheel. See how the zones respond!
If something looks off (e.g., wrong zone lighting), double-check the effect type and ensure no conflicting profiles are active.
Step 8: Save Your Custom Profile
Profiles let you switch between lighting setups easily—say, “Work Mode” vs. “Gaming Mode.” To save your current effect:
- Click the Profiles tab at the top.
- Click New Profile and name it (e.g., “Night Gaming”).
- Switch back to the Lighting tab and tweak further if needed.
- Return to Profiles and select your saved name.
Now, anytime you open iCUE, just select that profile to reload your preferred lighting. You can also assign profiles to specific applications via iCUE’s “Device Profiles” feature.
Advanced Tips for Maximum Flair
Sync with Other Corsair Devices
If you have a Corsair keyboard or headset, enable “Device Sync” in iCUE’s global settings. All devices will mirror the same lighting effect—perfect for immersive setups.
Use Audio Reactivity
Some iCUE effects respond to music or game audio. In the Lighting tab, look for “Audio Reactive” modes. These flash or pulse along with sound—great for streamers!
Create Layered Effects
Combine two effects: e.g., set the logo to “Breathe” while keeping the scroll wheel “Static.” iCUE allows overlapping zones for unique looks.
Troubleshooting Common Issues
Lighting Changes Don’t Appear
First, confirm iCUE recognizes your Scimitan. If the device icon shows a warning triangle, try:
- Updating iCUE to the latest version.
- Checking Device Manager for driver conflicts.
- Reinstalling iCUE completely (uninstall first, then redownload).
Mouse Not Detected by iCUE
Ensure the USB cable is fully inserted. Try another port—preferably rear motherboard headers. Disable any RGB software running in background (like Razer Synapse or Logitech G Hub).
Effects Reset After PC Sleep/Wake
This sometimes happens due to power-saving settings. In Windows Power Options, set USB selective suspend to “Disabled.” Also, ensure iCUE launches at startup.
Conclusion: Own Your Light Show
Changing lighting effects on your Corsair Utility Engine Scimitan is simple once you know the ropes. With iCUE, you have endless creative control over your mouse’s 17-zone RGB. From calming gradients to aggressive wave patterns, the choice is yours.
Remember to keep iCUE updated, save useful profiles, and don’t hesitate to experiment. Your Scimitan is more than a tool—it’s part of your identity. So make it shine!
