What You’ll Need
- Sky Lounge Roof Ambient Lighting Kit
Ensure you have the correct kit for your specific BMW X3 / X5 / X6 / X7 model. - Cleaning Solution (Glass Cleaner Formula)
Mix water and dish soap as follows:- For 500ml–750ml water: Add 3 drops of dish soap (about the size of a soybean).
- For 2000ml water: Add 7 drops of dish soap (about the size of a soybean).
Important: Do not use too much dish soap, as excessive soap will prevent the film from sticking properly.
When squeegeeing, first apply a cross pattern, then push water toward the four corners. Apply firm pressure and wipe clean in one continuous motion.
After installing the film, allow it to dry completely before installing the light strips. Installing the light strips too early may cause the film to peel off and become damaged if removed later.

Installation Steps:
Step 1: Film Installation Creating Your Canvas
This step is crucial for the overall look, so take your time!
Clean the Sunroof Glass Thoroughly: This is arguably the most critical part of film installation. Dust, fingerprints, or smudges will be trapped under the film and highly visible.
Spray your cleaning solution generously onto the sunroof glass.
Use a clean microfiber cloth to scrub the entire surface.
Wipe dry with a separate, clean, lint-free microfiber cloth. Inspect it closely for any remaining particles. Repeat if necessary!
Slightly dampen the sunroof glass again with your cleaning solution – this allows you to slide and position the film.
Carefully peel a corner of the protective backing from the film.
Align the film with one edge of your sunroof glass, ensuring it's straight.
Slowly peel back the rest of the backing while gently laying the film onto the wet glass.
Step 2:Spring Wire Installation
Route the spring wire along the edge of the sunroof frame as video.
You may need to gently pry back some interior trim pieces using your plastic trim removal tools to tuck the wire neatly and invisibly. Avoid forcing anything to prevent damage.
Ensure the wire is secure and won't sag or interfere with the sunroof's operation.
Next is the wiring process.
The wiring method may vary depending on the vehicle model. Please select the appropriate wiring method based on the color of the controller you received.
Once completed, please proceed to Step 4: LED Light Strip Installation.

Step 4: LED Light Strip Installation
Install the LED Light Strip: Carefully peel the adhesive backing from the LED light strip and install it into its designated mounting position, typically along the perimeter of the sunroof opening, just inside the frame.
Test the Lighting: Before you reassemble any interior trim, power on your car and test the lighting to confirm normal operation.
Check if the entire strip lights up evenly.
If your kit has color changing features, test them out.
