Compatible with all 12V vehicles. Operating temperature range: -20°C to +50°C.

 

The Interior Detail That Makes Everyone Stop and Stare

There is one car interior upgrade that generates more passenger reactions than any other. Not ambient strips. Not footwell lighting. Not door bowl lights.

The moment someone gets into a car with a fiber optic starry sky ceiling — and the roof comes alive with hundreds of individual points of light twinkling at different brightnesses, shifting through colours, pulsing to the music — every conversation stops.

Rolls-Royce has offered a Starlight Headliner as a factory option since 2006. The original system uses 1,340 fiber optic strands hand-stitched through a perforated headliner by a single craftsperson. It takes approximately 16 hours to install. The option price starts at $12,000.

The GUADSUN 16W Fiber Optic Star Ceiling Light creates the same constellation effect — the same twinkling, the same depth, the same night-sky atmosphere — through the same fundamental technology: a high-powered LED projector transmitting light through hundreds of individual fiber optic strands.

The difference is the price, the installation time, and the fact that you can take it with you when you change cars.

 

Who This Product Is For

This product is designed for:

• Drivers who want the single most visually dramatic interior upgrade available
• Car enthusiasts who want a genuinely unique interior that no one else in their social circle has
• Parents who want to create a magical experience in family vehicles for children
• Rideshare and taxi drivers who want passengers to remember the trip
• Car show participants wanting a standout interior detail
• Anyone who has seen a Rolls-Royce Starlight Headliner and wanted that effect in their own car

This product requires:
Willingness to spend 2–4 hours routing fiber optic strands through your headliner. This is the most installation-intensive product in the Veltrixa Auto catalogue. The result is proportionally more dramatic than anything else we carry — but it requires commitment during installation.

What Makes This Different From LED Strip Lighting

This is not an LED strip. It is not an acrylic light bar. It is not a projector that casts a pattern onto the roof.

The GUADSUN system works by transmitting light from a single 16W RGBW LED projector unit through hundreds of individual fiber optic strands — each strand terminating at a single point in your headliner. Each strand end appears as a single star.

Why this matters:

Individual point sources: Each fiber optic strand is one star. Not a pattern, not a projection, not an image — actual individual points of light emerging from the headliner surface itself.

The irregular turntable: The GUADSUN projector contains a built-in turntable with irregularly distributed holes of varying sizes. As this turntable rotates, different fibers receive light at different intensities and timings — some bright, some dim, constantly cycling. This is what creates the twinkling effect. Without this mechanism, all stars would be the same brightness at the same time — which looks artificial. The irregular rotation creates the random, shifting brightness that makes the effect look like an actual night sky.

Zero heat at the headliner: All heat is generated at the projector unit — which mounts out of sight, typically behind the rear seat or in the boot area. The fiber optic strands themselves transmit light without generating any heat at the point of emission. This means the headliner surface never gets warm, which is critical for the synthetic fabrics used in most Australian-market vehicle headliners.

RGBW — Four Lamp Beads, Not Three

Standard LED systems use RGB — Red, Green, and Blue — mixing these three colours to create the full spectrum including white.

The GUADSUN system uses RGBW — Red, Green, Blue, and a dedicated White lamp bead.

Why this matters in practice:

RGB white is produced by mixing red, green, and blue at equal intensity. The result is a white that has a slightly warm or cool cast depending on the exact balance — never a truly pure, clean white.

RGBW white comes from a dedicated white LED bead — producing a pure, accurate white that RGB cannot replicate. When you want a classic white starfield — the most realistic night sky effect — RGBW delivers it. RGB systems produce a white that experienced eyes immediately read as artificial.

The dedicated white bead also allows RGBW systems to produce more nuanced colour mixing — pastel shades, subtle tints, and colour combinations that four-bead systems achieve where three-bead systems cannot.

Thirteen Static Colours. Six Dynamic Effects. Voice Control.

Static colours (13 options):
Hold any single colour across your entire star field — white for a classic night sky, deep blue for an oceanic atmosphere, soft purple for a premium cabin feel, or any of the 13 available static options.

Dynamic effects (6 modes):

Voice control / music sync:
The built-in sound sensor detects the rhythm of music playing in your car and synchronises the star field's flash pattern and colour changes to the music frequency. Bass hits trigger one response, mid-range another — creating a reactive light show that pulses with whatever is playing through your speakers.

Control methods:

• Bluetooth app (download "LED LAMP" — available iOS and Android)
• Physical touch controls on the projector unit
• Remote controller (model dependent)

Technical Specifications

Understanding Fiber Optic Strand Options

The 20mm coupling aperture on the GUADSUN projector accepts three standard fiber optic strand diameters. The strand diameter you choose affects the visual appearance of your star field:

Recommendation for most vehicles: 0.75mm strands at maximum density create the most realistic night sky appearance — the individual stars are fine enough to look natural rather than mechanical, and the higher count creates the depth and randomness of an actual starfield.

⚠️ Fiber optic strands are not included in the base kit. The projector unit is sold separately from the fiber optic strands in most configurations. Check your selected variant at checkout for what is included, and ensure you have the correct strand type and quantity for your headliner coverage area.

Installation Overview

Honest assessment: This is the most involved installation in our catalogue. The result is the most dramatic. These two facts are directly connected.

What's required:

• Partially removing your headliner to route fiber optic strands through pre-drilled or pre-punched holes
• Routing strands cleanly from the coupling point on the projector to each star position across the headliner
• Mounting the projector unit in a concealed location — typically behind the rear seat headrest or in the boot area
• Connecting the projector to your 12V power system

Time required: 3–6 hours for a first installation. Experienced installers complete it in 2–3 hours.

Professional installation:
This product is suitable for professional installation by a car audio or automotive interior specialist. If you are not comfortable partially removing your headliner, professional installation is strongly recommended. The result justifies the cost — a professionally installed fiber optic ceiling is indistinguishable from a factory luxury option.

Key installation notes:

• The projector must be positioned so it does not obstruct rear visibility or passenger comfort
• Fiber strands must be protected from pinching at routing points — kinked or pinched strands will not transmit light
• Never cut or bend strands at sharp angles — fiber optic strands transmit light through internal reflection; sharp bends break the transmission path
• The projector unit generates heat — ensure adequate ventilation at the mounting location

 

Frequently Asked Questions

How many stars will my ceiling have?
This depends on the fiber optic strand diameter and how many strands you route through the headliner. With 0.75mm strands at full capacity, up to 560 individual star points are possible — comparable to the Rolls-Royce Starlight Headliner's 1,340 strands in a much larger headliner surface. For a standard passenger car headliner area, 200–400 strands creates a dense, realistic star field.

Does the projector get hot?
Yes — the 16W LED projector generates heat at the unit itself. This is normal and expected. The projector should be mounted in a ventilated location with clearance on all sides. The fiber optic strands themselves generate zero heat at the headliner surface — the heat stays at the projector.

Will this work in Australian summer heat?
The operating temperature range is -20°C to +50°C. Australian summer ambient temperatures are well within this range. The projector should not be mounted in a location that receives direct sunlight through glass — a boot-area or behind-seat mounting position is standard and thermally appropriate.

Can I use this with any fiber optic strands?
The 20mm coupling aperture is a standard size compatible with 0.75mm, 1.0mm, and 1.5mm fiber optic strands. Third-party strands of these diameters are compatible. Ensure strands are PMMA (plastic) fiber optic type — not glass fiber, which is not suitable for this application.

Is this difficult to install myself?
It requires comfort with partially removing your headliner to route strands. If you have done headliner work before, this is manageable. If you have not, we recommend either watching installation videos specific to your vehicle model before starting, or using a professional installer. The routing process — not the electrical connection — is where most people encounter difficulty.

What app do I use to control it?
Download the "LED LAMP" app. The QR code for download is printed on the projector unit packaging. Available on iOS and Android.

Can I take it out if I sell my car?
Yes — the projector unit disconnects from the 12V power and the fiber optic bundle. Removing the fiber optic strands from a headliner requires more work but is possible without permanent damage to the headliner in most vehicle types.
