Fits: 2022-2026 Honda Civic 11th generation sedan, including Si. Hatchback and Type R use different tail lights.
This set replaces both the inner lamps on the trunk lid and the outer lamps on the body.
Required Tools
- Ratchet
- 8mm deep socket
- 10mm socket
- Plastic trim removal tool
- Zip ties
Wiring Reference
Outer lights: green is the running light, red is brake, yellow is turn signal and black is negative.
Trunk lid lights: white is reverse, green is the running light, blue is fog light and black is negative.
Orange is the signal wire. Only the driver-side light has a fog-light harness, matching the blue wire. Before you plug each connector together, check that black lines up with black.
The two pages below are the factory installation sheet for these tail lights, showing the removal steps, the wire colors and the connector layout on the back of the lights.
Step 1: Remove the Trunk Lid Liner
Open the trunk and use a trim removal tool to pop out the plastic push pins securing the trunk lid liner. Carefully pull the liner down to reach the tail lights.
Step 2: Remove the Trunk Lid Lights
Remove the fixing screws and nut securing the inner tail lights on the trunk lid with a 10mm socket. Disconnect the factory plug and carefully pull the light out from the outside.
Step 3: Remove the Outer Tail Lights
Use the trim removal tool to pry off the trim panel beside the outer tail light, starting from the top. Remove the fixing screws on the side of the light with an 8mm socket, then use the trim tool to ease the light out, disconnect the harness and remove it.
Step 4: Install the Outer Lights
Line up the new outer tail light and push it into place.
Important: check the switch on the back of the light and make sure it is set to ON, or the animation will not work.
Step 5: Run the Center Light Bar Wire
Run the included harness from the outer lights to the trunk lid lights. Where it passes through the body, replace the factory rubber plug with the rubber plug fitted on the new outer light's harness, so the opening stays sealed and watertight.
Step 6: Install the Trunk Lid Lights
Install the inner tail lights on the trunk lid and connect the harness you just ran from the outer lights to power the full-width light bar.
Extra black plug: The new lights have one extra black multi-pin plug. It is only used on a non-US version of the Civic. US cars have nothing to connect it to, so leave it unplugged and tape it up so it cannot rattle.
Step 7: Test, Secure and Reassemble
Test the brake, turn signal and reverse lights on both sides. Then reinstall and tighten all mounting nuts, tidy the wiring with zip ties, and reinstall the trunk lid liner.
The standard version is now fully installed. The next section applies only to RGB models.
RGB Models: Star Light Running App Setup
1. Remote control pairing. The remote comes pre-paired with the lamps and switches to Red Light Driving Mode (static red, no flowing animation) with one press. If the remote does not work, press the brake pedal and hold the remote button for 10 seconds to pair it again.
2. Animation control. The app controls the running-light animations. The startup animation is preset and cannot be changed.
3. Download the app. Search for "Star Light Running" in the App Store or Google Play, or scan the QR code on the controller box.
4. Bluetooth connection. Open the app, tap Add Device (Figure 2), open the interface (Figure 3), and select the nearby device.
5. Adjusting modes.
- Dynamic mode: the number in the center of the blue box shows the current mode. Tap + or - to switch effects, or AUTO to cycle through all of them.
- Static color: drag the color wheel in the green box, or tap a preset color. This stops any running animation.
- Brightness: drag the slider in the first row of the red box.
- Speed: drag the slider in the last row of the red box.
Tip: if you used the older "Light Running" app and have trouble connecting, use "Star Light Running", the upgraded version.
Only one side responds? The left and right lights sync through a signal wire. Check that the sync wire between them is plugged in securely.
Common Issues and Solutions
Tail light does not turn on after installation. Check that the harness connectors are fully seated. Inspect the pins inside each connector; if any are bent, carefully straighten them with a small precision tool and reconnect securely.
Animation does not run. Recheck that the switch on the back of each outer light is set to ON.
Swap test. If a tail light still does not work, swap the left and right units to find out whether the issue is the light itself or the vehicle wiring.
App cannot connect. Turn on Bluetooth and Location Services on your phone (Android needs Location for Bluetooth scanning). The vehicle's running lights (parking lights) must be on to power the Bluetooth module. Keep other strong signal sources away from the vehicle.
Condensation inside the tail light. Temperature differences can cause light condensation, which is normal. Once the light has been on for a while and the internal temperature stabilizes, the moisture clears on its own. It does not affect brightness, performance, or lifespan.
