Installation
This section guides you through the process of installing your new RGB Car LED Bulbs. The installation process is generally straightforward, replacing existing festoon bulbs.
- Access the existing bulb: Carefully remove the cover of your car's interior light fixture (e.g., dome light, reading light, trunk light). You may need a small flat-head screwdriver or a plastic pry tool to gently unclip the cover.
- Remove the old bulb: Once the cover is off, carefully remove the existing festoon bulb. Be cautious as the bulb might be hot if it was recently on.
- Insert the new LED bulb: Select the correct size (31mm, 36mm, 39mm, or 41mm) RGB LED bulb. Insert the new LED bulb into the socket. Ensure it is seated firmly.
- Test the light: Before replacing the cover, turn on your car's interior lights to ensure the new LED bulb illuminates. If it does not light up, try reversing the polarity by flipping the bulb 180 degrees in the socket.
- Replace the cover: Once the LED bulb is working correctly, carefully reattach the light fixture cover.
- Remote Control Setup: The remote control requires a CR2025 battery (not included). Open the battery compartment on the back of the remote and insert the battery with the correct polarity.


Operation
The included 24-key remote control allows you to easily manage the lighting effects and colors of your RGB LED bulbs.

Remote Control Functions:
- ON/OFF: Turns the lights on or off.
- Brightness Up/Down: Adjusts the intensity of the light.
- Color Choosing (R, G, B, W, and color buttons): Selects a specific color or white light.
- FLASH: Activates a rapid color flashing mode.
- STROBE: Activates a bright and gradually fading in/out mode.
- FADE: Activates a smooth color transition mode.
- SMOOTH: Activates a red and blue flashing mode.
Note:
For optimal performance, point the remote controller directly at the signal receiver on the LED bulb.

Troubleshooting
- Light does not turn on:
- Check if the bulb is correctly inserted into the socket. Try flipping it 180 degrees to reverse polarity.
- Ensure the car's interior light circuit is receiving power.
- Verify the remote control battery is installed correctly and has sufficient charge.
- Remote control not responding:
- Ensure the remote control battery is not depleted and is inserted with correct polarity.
- Point the remote directly at the signal receiver on the LED bulb.
- Ensure there are no obstructions between the remote and the bulb's receiver.
- Lights are dim or flickering:
- Check the car's voltage supply to ensure it is a stable 12V.
- Ensure the bulb contacts are clean and making good connection.
- Difficulty synchronizing colors between multiple bulbs:
- Due to individual signal receivers, achieving perfect synchronization across multiple bulbs with a single remote can sometimes be challenging. Try operating them one by one or adjusting from a central position.
User Tips
- Voltage Check: Always ensure your car's electrical system provides a stable 12V DC to avoid damaging the LED bulbs.
- Clean Contacts: Before installation, clean the mounting area and bulb contacts for better electrical connection and performance.
- Separating Bulbs: If the bulbs are connected in a strip, they might need to be carefully scored and separated before installation.
- Color Accuracy: Be aware that the "white" color setting might have a slight blue tint.
- Remote Range: The remote works best when pointed directly at the bulb's signal receiver.
