RGB Bluetooth LED Underbody Ambient Lighting

RGB LED underbody lighting: your car changes mood at the touch of a button

This RGB LED car ambient lighting kit installs light modules in the wheel wells and under the side skirts, where the light reflects on the asphalt. At night, the car appears to sit on a colored halo; at a car meet parking lot, it becomes the vehicle everyone photographs. Swipe on your phone and the entire spectrum flows by: deep red, electric cyan, slow gradient, or pulsing to the beat of the music.

The colored signature of the RGB underbody kit

Each module emits a dense, saturated light, not the pale glow of cheap adhesive strips. Arranged in groups of four or eight, they draw a continuous line under the car and project color onto the road. In gradient mode, the hues glide slowly from one module to the next; in static mode, a single color is frozen to highlight the body line. This multicolor car LED kit works just as well as a discreet welcome light as it does for a bold showpiece.

The most spectacular mode remains the microphone-based music synchronization: the kit picks up ambient sound and makes the modules beat to the rhythm of the bass. No connection to the car stereo is necessary, avoiding any console disassembly.

IP68, ABS, 12 volts: the construction of these lighting modules

The housings are made of ABS and have an IP68 protection rating—the expected level for a part exposed to road spray, road salt, and high-pressure washing from a reasonable distance. The stated operating range is from -20°C to 80°C, and the diode lifespan is rated at 100,000 hours. Power is supplied via 12 V DC from the onboard circuit using the provided cable. The kit carries the BOOMSUP brand and a CE certification.

• Choice of 4 or 8 LED modules—four wheel wells, or full underbody coverage.
• Bluetooth app control—the Lotus Lantern app provides access to colors, modes, and intensity.
• IP68 protection—designed to live under the car, not inside the cabin.
• Flashing music mode—the modules pulse to the rhythm detected by the microphone.
• 12 V installation—connects to the onboard circuit, without an external power supply.
• Compact ABS housings—discreet when turned off, invisible from the outside.

Properly mounting the modules under your car

The kit comes with its mounting accessories and instructions. First, locate the anchor points in the wheel wells, away from direct gravel spray and hot exhaust components. Secure the modules, route the wiring harness along existing components, and protect each sheet metal opening. Installing an underbody LED kit is done with the vehicle on jack stands or a lift; allow a good half-day for a neat job, hidden wiring included. Check the regulations applicable in your country: the use of certain colors on public roads is restricted.

Can you drive with the lights on?

This is the question that comes up in every forum. In France, non-approved exterior ambient lighting is used while stationary, on private property, or for display; red and blue colors are particularly sensitive under traffic laws. The kit therefore remains a styling accessory, to be turned off before getting back on the road. This is not a trivial limitation—it is better to keep it in mind before buying rather than after.

Your car LEDs chosen by lighting enthusiasts

Lighting is one of the areas where we refuse the most references: too many kits claim a level of protection they cannot maintain for three winters. We favor truly sealed housings and properly sheathed wiring harnesses. Have a question about the number of modules suited to your vehicle before ordering your RGB LED lighting kit? Our French-speaking team will guide you.

Choose 4 or 8 modules, and give your car a lighting signature that won't be forgotten.
