Yielinth LED Underglow Kit for Car — 4‑pc 12V (2×35" & 2×47") Waterproof, App + Music Sync

Yielinth LED Underglow Kit is a complete, weatherproof 12V lighting system that adds customizable RGB undercarriage illumination with app and remote control plus music-sync and DIY color modes.

Give your vehicle a bold visual upgrade with an underglow system designed to balance brightness, durability, and flexible control. This kit contains four waterproof LED strips in a two-line layout, a Bluetooth app and remote interface, music-synchronized effects, and multiple power options so you can mount it on cars, SUVs, trucks, vans and more.

How bright and responsive are the lights during music playback?

The kit uses high-intensity 3-in-1 RGB LEDs and a sensitive built-in microphone to create vivid, beat-driven lighting. The sound-sync responds in real time, letting the strips pulse or strobe with music, engine notes or ambient sounds for dynamic visual impact.

• 3-in-1 RGB chips for rich color saturation
• Built-in microphone for accurate music synchronization
• Adjustable speed, brightness, and strobe frequency in the app

What control options and customization are available?

Control the lights with either the Bluetooth smartphone app or the included handheld remote. The app unlocks 16 million colors, multi-color gradients, preset modes, and a DIY palette for saving custom themes, while the remote offers quick access to common effects.

• Bluetooth app: full RGB, DIY color storage, mode editing
• Infrared remote: instant mode, brightness, and color switching
• Fine controls: speed, brightness, and strobe adjustments

How simple is installation and will it survive outdoor conditions?

Installation is straightforward: strong adhesive backing, cable ties, and either a 12V cigarette-lighter plug or direct wiring to your vehicle’s battery. All strip joints are sealed and the system carries an IP68 rating, so it resists water, mud, and typical road grime.

• 2-line configuration fits many vehicle undercarriage layouts
• 12V cigarette-lighter adapter or direct positive/negative wiring
• IP68 waterproofing and sealed junctions for harsh weather

What sizes and vehicle types does this kit fit?

The package includes two shorter and two longer strips (two 35" and two 47" pieces) arranged across two parallel lines to cover common wheelbase and rocker panel layouts. The flexible tubing and adhesive allow mounting on cars, SUVs, trucks, motorcycles, and even boats or off-vehicle uses like patios.

• Strip lengths: 2 × 35 inches and 2 × 47 inches for adaptable coverage
• Flexible tubing conforms to curved rocker panels and frames
• Works on a wide range of 12V vehicles and non-vehicle applications

Who is this for? The Yielinth LED Underglow Kit is aimed at car enthusiasts, show drivers, and anyone who wants a reliable, weatherproof undercarriage lighting solution with rich color control and music-reactive features. It’s also a practical choice for weekend installers who want a plug-and-play option with adhesive mounting and for customizers who need DIY color modes and app-level precision.
