RGB LED Ambient Lighting for Car Interior with Bluetooth

RGB LED underbody lighting: your car set on a halo of color

There is the car parked in front of the club, and then there is the one floating on a carpet of light. This RGB LED underbody lighting consists of ultra-flat modules that screw into the chassis, wheel wells, or under the side skirts, projecting a colored sheet onto the asphalt. In a few seconds, the silhouette of your vehicle stands out from the rest of the parking lot. It's the underglow effect seen on American builds, available here as a ready-to-install kit.

Discreet modules by day, a spectacular halo by night

Each module is barely larger than a coin and hides completely behind a skirt or wheel well. By day, a matte black shell that no one notices. At night, a wide and saturated projection that reflects up onto the rims and highlights the tire tread. On a lifted 4x4 or a pickup, the effect is even more pronounced: the ground clearance allows the underbody light to spread freely.

Colors are selected by hand on a color wheel, with smooth transitions or sharp changes. The music synchronization mode makes the modules pulse to the beat of the car stereo: a simple control box picks up the sound and animates the entire kit in real time.

What these RGB modules exposed under the car are really worth

Underbody lighting lives in the worst environment for a car: water spray, road salt, gravel. The modules selected here are resin-poured in a waterproof shell, with a peripheral lip that prevents water from pooling on the light-emitting surface, and cables encased in a single piece up to the box. Each pod packs a high-density RGB diode matrix: the output remains clear even in full city lighting.

The central box is controlled via Bluetooth from an app: colors, brightness, animation speed, preset modes. A small physical switch on the wiring harness allows you to turn everything off without taking out your phone. The whole thing runs on 12 V from the vehicle's battery.

• Kit of 4, 6, or 8 modules — 4 for the wheel wells, 8 to completely surround a large bed
• Bluetooth app control — color, intensity, and animation set from the phone
• Reactive music mode — the modules pulse in rhythm with the sound in the cabin
• Resin-poured waterproof shells — designed to withstand life under the chassis, rain and spray included
• Pre-wired harness with switch — direct 12 V connection, manual shut-off possible
• Ultra-flat format — invisible by day, no wind resistance, no risk of snagging

Installing this kit under your car: locate, screw, route

The principle is simple but deserves a little method. First, locate the existing mounting points under the wheel wells and side skirts, position the modules dry to check the orientation of the light beam, then screw them in and route the cables along the original harnesses with zip ties. The installation of underglow lighting is best done on a lift or ramps; allow two to three hours for a clean job.

The kit is universal and suitable for sedans, SUVs, 4x4s, and pickups in 12 V; lowered vehicles simply require moving the modules back to avoid rubbing. On open roads, check local regulations: decorative exterior lighting is generally reserved for stationary use, on a track, or for display.

How many modules do you need to properly cover a car?

Four modules are enough to light up the four wheel wells of a city car or a compact car, with a halo centered on the rims. Six modules allow you to add two points on the side skirts and remove the shadow zone in the middle of the vehicle. Eight modules are the right choice for an SUV, a long station wagon, or a pickup: the sheet becomes continuous from end to end. If you hesitate, go for the higher version: you rarely regret an over-equipped rock lights kit, the opposite is frequent.

Choosing your exterior lighting at Becquet Voiture

Automotive styling is our everyday business, and decorative lighting is part of it just like bodywork. We favor kits whose modules are truly waterproof and whose harnesses are long enough to be neatly routed, because a poorly designed LED underbody light won't make it through the first winter. Our French team helps you choose the number of modules suited to your vehicle.

Select your kit of 4, 6, or 8 modules and give your car a light signature that no one can ignore.
