RGB LED Underbody Lighting for 4x4 SUV

RGB LED underglow: your 4x4 finally emerges from the shadows

This 4x4 and SUV underglow kit doesn't use flexible strips: it screws rugged LED modules into the wheel arches, under the running boards, and along the chassis rails. The result is a wash of color rising from the ground and filling the wheel wells, rather than just a line along the lower bodywork. On a lifted vehicle, this is the only way to achieve under-vehicle LED lighting that truly fills the space.

RGB modules in the wheel arches: the effect on a lifted SUV

Each module projects a wide, short beam. Mounted in pairs above the wheels, they illuminate the rims from the inside and create a colored halo that makes the vehicle stand out from the asphalt. Deep purple creates an almost surreal effect on light-colored paint, warm amber evokes the world of off-road preparation, and pure white simply serves as work lighting at the campsite.

The more modules you add, the more continuous the effect becomes: four modules highlight the four wheels, eight add the lower bodywork, and twelve or fourteen fill the undercarriage and the rear. This RGB underbody lighting is controlled from your phone, module by module or as a single scene.

Aluminum housing, resin, and seal: why these modules withstand mud

A lighting accessory living under an off-roader endures gravel, mud, pressure washing, and frost. These modules are built to withstand it with a compact metal body, a lens encased in resin, and a peripheral seal: this is waterproof LED lighting for 4x4s, not a decorative string of lights. They are secured with a single screw, allowing you to aim the beam after tightening.

The included wiring harness connects all the modules to a 12V central control box. The connectors are keyed: it is impossible to reverse the polarity. The mobile app control provides access to solid colors, gradients, slow flashing, and music synchronization.

• Kit of 4 to 14 RGB LED modules — size the kit according to the vehicle's dimensions and the desired effect
• Modules that screw under the vehicle — mechanical screw mounting, far more durable than simple adhesive on an off-roader
• Rugged body and resin lens — designed for mud, gravel, and pressure washing
• 16 million colors controlled via smartphone — saved scenes, variable intensity, music mode
• Auxiliary lighting at the campsite — in full-power white, the modules serve as work lights around the vehicle
• Complete wiring harness included — keyed connectors, central control box, 12V power supply

Positioning the modules under a 4x4: the mounting plan that works

Start with the four wheel arches, aiming each module toward the inside of the rim: this is where the photo effect is strongest. The next modules go under the lower bodywork, halfway between the wheels, and then under the rear bumper. Avoid the exhaust, steering components, and any moving parts, and leave some slack in the wiring at the wheel assemblies. Installing LED modules under an SUV takes about two hours and requires light drilling in non-structural areas; if you are unsure about a mounting point, have a workshop check it. Universal kit: check the ground clearance and mounting points of your vehicle before installation.

How many modules are needed for a pickup truck or large SUV?

For a compact SUV, six modules are enough to achieve an even effect. For a large SUV or double-cab pickup truck, allow ten to twelve modules; otherwise, dark areas will appear between the wheels and the halo will lose its continuity. The fourteen-module kit is designed for lifted vehicles where you also want to illuminate the chassis and differential. When in doubt, measure the distance between the front and rear wheels: if it exceeds three meters, step up the number of RGB LED modules.

Preparing your 4x4 with Becquet Voiture

Our job is to create accessories that change a vehicle's appearance without betraying its purpose. With automotive underglow kits, we first look at the mounting mechanism and waterproofing: a module that takes on water after the third wash has no place in a serious catalog. Have a question about the number of modules, the length of the wiring harnesses, or the connection? Write to us in French, and we will provide useful answers.

Choose your number of modules and give your 4x4 this wash of color that will turn heads as soon as night falls.
