Yielinth Car Underglow Lights Kit, 4‑Piece LED Strips — App & RF Remote, IP67 Waterproof, 16M Colors

Yielinth Car Underglow Lights are a complete, weatherproof LED undercarriage kit that adds customizable RGB illumination to your vehicle via app or RF remote.

This underglow kit includes four flexible LED strips, a control box, smartphone app and 24-key RF remote so you can change colors, activate music sync, set timers and adjust brightness. Built from sealed rubber tubing and IP67-rated components, the system is designed to withstand wet roads while delivering intense light from 252 high-output 3-in-1 LEDs. The wiring harness and mounting accessories simplify installation on most 12V cars, trucks and SUVs.

How bright and varied are the colors?

The strips use dense 3-in-1 RGB LEDs to produce vivid light and a wide color range, including 16 million shades through app control. Brightness can be tuned to match show settings or subtle accent lighting, and strobe speeds are adjustable for dynamic effects.

• 252 high-intensity RGB chips for strong, even illumination
• App-driven 16 million color options and custom DIY scenes
• Brightness and strobe speed controls for tailored visibility

What control methods and special modes are available?

You can operate the system via Bluetooth app on your phone or the included 24-key RF remote; both give access to presets, DIY color slots, timing and brightness. A built-in microphone enables music sync so the lights pulse and change with sound, while the remote offers quick access when your phone isn’t handy.

• Smartphone app for precise color selection and scene creation
• 24-key RF remote for instant mode switching and brightness control
• Music-sync mode using the control box’s sensitive mic

Will these lights hold up in rain and road grime?

The strips are encased in flexible, sealed rubber tubing and rated IP67 for water and dust resistance, helping them withstand splashes, puddles and everyday road conditions. The connectors and inline fuse add protection for the vehicle’s electrical system when installed correctly.

• IP67 waterproof and dustproof construction for outdoor use
• Fully sealed LED strips to prevent moisture ingress
• Inline fuse and robust connectors for safer installation

How easy is installation and where can I mount them?

The kit arrives with two 47.2-inch and two 35.4-inch strips, a 32-foot wiring harness, adhesive backing, clips and cable ties for flexible mounting on most 12V vehicles. Strips bend to follow contours and can be mounted under wheel wells, along rocker panels, inside footwells, or repurposed for ambient home or event lighting.

• Two long and two short strips to cover a full undercarriage layout
• Strong adhesive tape plus cable ties and clips included
• Cigarette-lighter plug and hardwire leads with inline fuse for power options
