BMW 5th 3 Series F30F35 Tail Lights
Installation Guide
Required Tools:
- 10mm Socket
- 8mm Socket
- Ratchet/Impact Driver
- Phillips Screwdriver
- Flathead Screwdriver or Trim Tool
- Electrical Tape/Zip Ties
Step1: Remove Trunk Liner Clips
Open the trunk. Use a Phillips screwdriver to gently unscrew the center of the plastic expansion clips securing the liner, then pull them out. Remove all clips to access the inner tail lights.
Step2: Remove Inner Tail Light
Unplug the power connector from the inner tail light. Use a socket wrench to remove the single nut securing the light assembly (usually 8mm or 10mm).
Step3: Slide Out Inner Light
From the outside, press the plastic tab on the side of the tail light and slide the assembly outward to remove it from the trunk lid.
Step4: Remove Drip Rail Cover
Move to the outer tail light on the body. Use a flathead screwdriver or pry tool to carefully remove the black plastic drip rail cover above the tail light.
Step5: Remove Outer Mounting Nuts
Use a 10mm socket to remove the two nuts securing the outer tail light assembly.
Step6: Pull Out Outer Light
Grasp the tail light assembly and pull it straight back to release it from the guide pins. Then, disconnect the power plug.
Step7: Install New Outer Light
Align the guide pins of the new light with the body holes, connect the power harness, and push the light into place. Reinstall and tighten the two 10mm nuts.
Step8: Install Inner Light & Test
Slide the new inner light into the trunk lid slot, tighten the nut, and connect the power. Note: For Pre-LCI models, you may need to connect the included bridge harness (route the yellow wire through the trunk hinge rubber tube) for signal synchronization. Test all functions before finishing.
The following section applies ONLY to RGB Models. If you purchased the standard version, your installation is complete.
Note: If the lights do not illuminate after installation, please see the last page:

RGB / App Connectivity Issues
If you are experiencing connection or control issues with the RGB app, please check the following:
Phone Settings & Power: Ensure your phone's Bluetooth is turned ON. Ensure Location Services (GPS) are turned ON (required for Bluetooth scanning on Android).
Important: The vehicle's Running Lights (Parking Lights) must be turned ON to power the Bluetooth module.
Signal Interference: Make sure there are no other strong signal sources inside or near the vehicle that could interfere with the connection.
RGB / App Connectivity Issues
If you are experiencing connection or control issues with the RGB app, please check the following:
Phone Settings & Power: Ensure your phone's Bluetooth is turned ON. Ensure Location Services (GPS) are turned ON (required for Bluetooth scanning on Android).
Important: The vehicle's Running Lights (Parking Lights) must be turned ON to power the Bluetooth module.
Signal Interference: Make sure there are no other strong signal sources inside or near the vehicle that could interfere with the connection.
App Installation & Troubleshooting:
1. Remote Control Pairing:
The remote control comes pre-paired with the lamp. It allows a one-key switch to "Red Light Driving Mode" (static red, no flow animation).
To Re-pair: If the remote does not work, press the brake pedal and hold the remote control button for 10 seconds to complete the pairing.
2. Animation Control:
The RGB lamps allow you to control the running light animations via the APP. (Note: The startup animation is preset and cannot be adjusted.)
3. APP Download:
Search for "LightRunning" (or "Star Light Running") in the App Store/Google Play Store, or scan the QR code on the controller box to download.
4. Bluetooth Connection:
Open the App, click Add Device (Figure 2), enter the Interface (Figure 3), and select the nearby device to complete the Bluetooth connection.
5. How to Adjust Modes:
5.1 Dynamic Mode: The number in the center of the blue box indicates the current mode. Click + or - to switch between different dynamic effects. Click AUTO to cycle through all modes automatically.
5.2 Static Color Mode: Drag the color wheel in the green box interface, or click the preset color buttons to switch to a static, solid color. This will immediately interrupt any playing animation.
5.3 Brightness Adjustment: Drag the slider in the first row of the red box to adjust the brightness.
5.4 Speed Adjustment: Drag the slider in the last row of the red box to change the speed of the animation.
Pro Tip: If you previously used the "Light Running" app and are having connectivity issues, please try downloading "Star Light Running". This is the upgraded version of the App.
Synchronization Check:
Most RGB kits use a physical wire to sync the left and right lights. If you can only control one side via the App, please check the Sync Signal Wire connecting the two lights to ensure it is plugged in securely.
Common Issues & Solutions
1. Tail light does not turn on after installation
Please first check whether the wiring harness connectors are properly connected and fully seated. Inspect the pins inside the connector to ensure none are bent or misaligned.
If any pins are bent, you may carefully straighten them using a paper clip or other small precision tool, then reconnect the plug securely.
2. Swap test
If the tail light still does not illuminate, try swapping the left and right tail lights to determine whether the issue is related to the light unit itself or the vehicle wiring.
3. Condensation inside the tail light
Condensation may occur due to temperature differences, which is a normal physical phenomenon. After the tail light has been operating for a period of time and the internal temperature stabilizes, the moisture will naturally dissipate.
This does not affect brightness, performance, or the lifespan of the tail light.
