Fits: 2018-2022 Honda Accord 10th generation sedan, including Hybrid.
This set replaces both the inner lamps on the trunk lid and the outer lamps on the body.
Required Tools
- 10mm socket and ratchet
- Plastic trim removal tool
- Phillips screwdriver
- Zip ties
Part 1: Remove the Factory Tail Lights
Step 1: Remove the Trunk Lid Trim
Open the trunk. Use a trim removal tool to pop out all the plastic push pins securing the trunk lid liner, then remove the liner to reach the inner tail lights.
Step 2: Disconnect the Inner Tail Lights
Find the connector for each inner tail light on the trunk lid. Press the release tab and disconnect the plug.
Step 3: Remove the Inner Tail Light Nuts
Use a 10mm socket to remove the nuts securing the inner tail light. Keep the nuts; you will reuse them.
Step 4: Remove the Outer Tail Lights
Peel back the trunk side liner to reach the outer tail light fasteners. Remove them and pull the tail light straight back to release it from the body.
Part 2: Wiring and Installation
Step 5: Run the Harness Through the Grommet
Remove the factory rubber grommet and feed the harness of the new inner tail light through the hole so it can connect to the outer light. Press the grommet fully back into place to keep water out.
Step 6: Connect the Inner and Outer Lights
Connect the included extension harness between the inner (trunk lid) and outer (body) tail lights so the sequential signal runs across both sections.
Step 7: Install the New Lights
Line up the new tail lights, push them into place and secure them with the factory 10mm nuts. Do not overtighten. Secure the harness with a zip tie at the point shown.
Part 3: Test and Finish
Step 8: Test Every Function
Turn on the ignition and check the brake, turn signal, reverse and running lights on both sides before reinstalling any trim.
Step 9: Reinstall the Trim
Secure any loose wires with zip ties, then reinstall the trunk lid liner and push the plastic clips back in.
The standard version is now fully installed. The next section applies only to RGB and Digital models.
RGB and Digital 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.
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.
