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.
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.
