Yielinth LED Underglow Kit for Cars, Trucks & SUVs — 4-Strip (2×35"+2×47") RGB, App & Music Sync

The Yielinth LED Underglow Kit is a complete, weatherproof 12V lighting system that adds customizable RGB illumination under cars, trucks, and SUVs with app, remote, and music-synced controls.

Designed for drivers who want bold, programmable accent lighting, this kit bundles four flexible LED strips (two 35-inch and two 47-inch), a Bluetooth controller, remote, and all mounting hardware. With 16 million color options, 29 dynamic modes, a DIY scene builder, and a responsive microphone for sound-reactive effects, it turns vehicle exteriors into an attention-grabbing light show while remaining simple to install and robust enough for everyday road use.

How does the system sync with music and respond to sound?

The built-in sensitive microphone captures ambient audio and drives the LED patterns to pulse, flash, or flow in time with beats and melodies. Use music-sync modes via the app or choose preset rhythmic patterns with the remote for instant audio-reactive visuals.

• Onboard microphone for accurate beat detection
• Multiple music-sync style options (pulse, flash, wave)
• Adjustable sensitivity and speed directly from the app
• Works with car audio and external sound sources

What mounting and power options are available for different vehicles?

The kit includes a 2-line layout that fits most vehicles—two shorter 35-inch strips for front/rear and two longer 47-inch strips for sides. You can power it using the included 12V cigarette-lighter adapter for a plug-and-play setup or hardwire it to the vehicle’s battery with the supplied positive/negative leads for a permanent installation.

• 2-line design supports custom placement on cars, trucks, SUVs, vans, motorcycles
• Strong adhesive backing plus cable ties for secure attachment
• Cigarette-lighter plug for temporary use and direct wiring for permanent fit
• Flexible tubing and bending capability to follow chassis contours

How durable is the Yielinth underglow for outdoor and seasonal use?

Built to handle road conditions and weather, the strips are fully sealed and rated IP68, which protects against dust and prolonged water exposure. Temperatures between -20°C and 40°C (-4°F to 104°F) won’t stop them, and glued junctions prevent moisture ingress at connection points.

• IP68 waterproof rating for rain, splashes, and puddles
• Sealed junctions with glue reinforcement for extra protection
• Durable materials resist UV, salt, and road grime
• Wide operating temperature range for year-round reliability

What control features and customizations can I expect?

Control the lights with the Bluetooth mobile app or the included RF remote for fast changes without your phone. The app unlocks full customization: choose any of 16 million colors, build multi-color gradients, save DIY scenes, and fine-tune brightness, speed, and strobe frequency.

• Bluetooth APP control with color picker and mode library
• 29 built-in dynamic modes plus user-defined DIY presets
• Remote control for quick mode or color changes
• Fine adjustments for brightness, speed, and strobe settings

Who is this for? If you want striking underbody lighting that’s versatile enough for casual show-offs and serious installers alike, Yielinth’s kit fits the bill. It’s ideal for car enthusiasts, weekend customizers, show vehicles, and anyone who needs a durable, weatherproof RGB underglow with both plug-and-play convenience and permanent wiring options.
