Freightliner Cascadia LED Under-Cab Accent Light Kit

Designed to fit the newer Freigtliner Cascadia body style (2018+) this under-cab lighting kit is available in both SINGLE COLOR and MULTI-COLOR (RGB) versions. This Under-Cab LED light kit contains 228 super bright 5050 LEDs in 10 surface mounted low-profile hi-intensity LED strips (5 LED strips for each side of the truck). These LED strips are designed to light up the area between the cab and the side skirts (see photos). On each side, four of these surface mounted LED strips attach to the inside of the lower body skirt facing inward. The fifth LED strip mounts to the driver (and passenger) door facing downward which floods the steps on both sides of the truck with light. The LED strips have been sized to fit 2018+ Freightliner Cascadia body styles regardless of fuel tank openings. This kit can be used by itself or, can be paired with our Freightliner Cascadia Under-Glow LED light Kit as well as our Cascadia Grill & Air Vent LED Light Kit as shown in the photos above. For multi-color RGB kits, the Heavy Duty LED Controller (or Dual Zone Heavy Duty LED Controller) offered in this kit will power all LEDs in all three LED light kits. You only need one LED controller. NOTE: The truck pictured on this product page has ALL of our Cascadia LED light kits installed: Under-Cab (this kit), Under-Glow, Grill/Air-Vents and Rear Fairing Accent Light with Tail Turn Brake Integration.

The multi-color RGB version provides over 16 million color combinations that you control and includes it's own on/off wireless switch. The multi-color RGB kit includes our HEAVY DUTY Combo Bluetooth + RF M7 controller so you can control the lights with your Bluetooth enabled smartphone or the included wireless RF remote control. With any of the Boogey Lights® BLUETOOTH controllers you can control your lights with your Bluetooth 4.0 enabled Android or IOS smartphone. These high-tech controllers are capable of displaying 16 million different color combinations. In addition, lighting effects on the Smartphone controller are significantly more controllable in terms of speed and intensity. Each color and lighting effect is controlled by "sliders" or a color square on your smartphone screen so you can adjust the speed and intensity to get the lighting exactly the way you want it. Our controllers operate on 12vdc. Also, all of our SERIES 2 Bluetooth Combo controllers include an RF remote control allowing for quick on/off of the controller. You can operate this controller with the included RF wireless remote OR you can use your Bluetooth 4.0 enabled smartphone and our free smartphone APP (Android and IOS).

The single color version is available in your choice of one of six super-bright colors: Amber, Red, Green, Blue, White or Pink. Also, you have your choice of BLACK or WHITE PCB. With the single color version you'll need to either add your own on/off switch or wire them into an existing circuit using a relay.

This Under-Cab LED Light Kit is designed as an UNDER-CAB accent light strip that is hidden; providing indirect lighting.  It is intended to be affixed to the truck's body (hidden from view) below the point at which the side fairings cover the light strips. This kit is not intended to be used as a side marker light facing outwards.  DO NOT MOUNT THEM in a way that the LEDs may be facing into the field of vision of other drivers. 

DOT COMPLIANCE: The AMBER and RED single color LED strips are DOT COMPLIANT. They conform to applicable provisions of the Federal Motor Vehicle Safety Standard 108 requirements.

More About the Boogey Lights® Bluetooth Smartphone APP
Under-Cab LED light kit with 228 LEDs consisting of 10 different LED light strips with power leads. Mounting and suggested placement diagram included.
RGB/Multi-Color: Wireless RF + Bluetooth Combo RGB Heavy Duty LED controller with M7 Style wireless remote. This is a single zone LED controller required to operated multi-color RGB leds. For those wishing to add our other Cascadia light kits to their truck, we also offer a DUAL ZONE Heavy Duty LED controller which provides the ability to segment your lights into two distinct zones if desired.
Single Color: Single color LEDs do not require an LED controller to operate. They do however require a switch somewhere in the circuit to turn them off/on. There are a number of ways to do this but regardless of how you decide to switch your single color LEDs, you need to be mindful of the amperage that 228 LEDs will draw. If you're considering adding these LEDs to an existing circuit (e.g. with your existing marker or running lights) we strongly suggest using a relay vs simply tapping into the existing circuit. This especially important on newer trucks where the LCM will likely throw an error when you add 228 more LEDs to the system.
Installation supplies includes wiring kit, feeder cable, 3M Adhesion Primer, 2 - 90 degree angle aluminum for mounting the LED strips on the driver and passenger's side to the truck body, 3M quick-lock, split loom.
Installation Manual and Wiring Diagram
Warranty Information: This led light kit uses our Low Profile Hi-Intensity Surface Mounted LED light strips. Where and how these light strips are installed make all the difference in their durability and thus, our warranty. If the lights in this kit are installed according to our instructions, we offer a ONE YEAR ORIGINAL OWNER WARRANTY against manufacture or product defect. The warranty is void however if the light kit is not installed according to the instructions.

OTHER ITEMS YOU MAY NEED TO COMPLETE YOUR INSTALL. No two installation scenarios are the same. Not everyone shares the same installation quality goals. Some folks are OK with twisting wires together, others want to solder them. Some folks are OK with running wires where they may be seen or unprotected to save money/time, others want a tidy, clean install without any wires showing. Some folks are OK with mounting their LED strips to whatever surface they can find, others want to take the time necessary to build out appropriate mounting surfaces to provide the best lighting effect on their vehicle. The point is it's not possible to provide all the materials necessary for all installation scenarios and quality goals. Our light kits provide the essential components needed for a high-quality, functioning lighting system. Installation of our light kit to your specific vehicle may however require additional items to make it look and fit the way you want. This is particularly the case with electrical wiring and mounting of LED strips. Before proceeding with your installation we suggest you consider THESE OTHER ITEMS.


Installation of this led light kit takes 4 to 5 hours to do it properly. You can download the Installation Manual directly from our website to get an idea of what's involved.

There are 10 different mounting locations in this kit (5 on each side of the truck) and all of the power leads need to be carefully run. DIYers will need to be familiar with removing the side skirts on the passenger's side of the truck as well as the driver's side. You also need to remove the steps on both sides of the truck. For the multi-color version of this kit, the LED controller is mounted in either the driver's side storage / jockey box or passenger's side. The passenger's side is usually less cluttered. You will need to drill a hole in the floor of that box to connect power to the battery box, led wires and antenna. All of the LED strips include a power lead. Each side skirt has four LED strips which are fastened to the inside of the skirt (see photo on INSTALL TAB for placement). A quick-disconnect connector is added in the event the side skirt needs to be removed in the future so the lights aren't damaged. Repeat for both sides. The fifth LED strip is secured to the bottom of the door shinning downward on the steps. This is done on both sides of the truck. The power lead from the door LED strip along with the side skirt power lead need to be routed to the LED controller (or switching mechanism if you're doing single color). Be sure to wrap all power lead wire in split loom which is included in the kit. The LED controller should connect directly to the battery bank with the included fuse holder added at the battery. Our installation manual includes more detail on all of this including photos of the suggested mounting locations for each strip. We do not however include detailed instructions on how to remove the side skirts/steps. We assume anyone attempting to install this light kit has the knowledge to do this already (or, is willing to figure it out on their own using any number of online sources).

LED Placement

These are the LED placement locations we used for this kit. It's important to follow this placement pattern to ensure the LED strips are protected. Mounting them in any other way voids warranty. Refer to the diagram below with numbered placements.

Driver's Side

  • Under Door: 1 - 45 LED strip mounted to the bottom of the driver's side door. The power lead for this strip is routed through the door jamb with the other wires and then back to the LED controller.
  • 4 - LED strips mounted inside the driver's side skirt facing inward toward the truck. See photo for placement.

Passenger's Side

  • Under Door: 1 - 45 LED strip mounted to the bottom of the driver's side door.
  • 4 - LED strips mounted inside the driver's side skirt facing inward toward the truck. See photo for placement.

LED Controller

  • The LED controller is mounted in either the driver's side or passenger's side storage area. The red 12vdc+ power lead needs to connect to the battery box (with fuse). The black 12vdc - power needs needs to be connected to a good metal ground.

Note on color selection: Amber (and Red if facing toward the rear) are the only colors that can be used while driving. If you're buying RGB lights, the Bluetooth controller allows you to setup presets for your color selections as well as features which include dimming, strobing, breathing and color blending. In our demo truck we have one button pre-programmed for orange/amber which we also dim by 50% so it isn't so bright. Be aware however you cannot get a true ORANGE or AMBER with RGB leds. WHY NOT?. You can come close by mixing equal parts RED + GREEN (and then increasing the intensity of the red just a little) using your phone and our Bluetooth APP but it is not precise. More details about this can be found here.

The Boogey Lights® Bluetooth controller included with this light kit also has our new SERIES 2 firmware which gives you the ability to program the controller to display two or three colors of your choice and then rotate those colors in sequence. For example, let's say it's Fourth of July and you want your lights to rotate through the color sequence of RED, WHITE and BLUE . Or, perhaps your favorite sports team's colors are Red and White and you want your lights to continually rotate through a color sequence of RED and WHITE. This SERIES 2 firmware controller and smartphone APP will do that - and more. You can for instance vary the speed of the sequence as well as the brightness. You can also choose from one of two different sequencing effect modes: BREATHING or ROLLING. Additionally, you can save these configurations in up to 3 presets such that you're able to recall the lighting configuration with a press of a button.



Why does the Printed Circuit Board (PCB) Matter? LED lights are mounted to a Printed Circuit Board (or PCB for short). The color of that PCB makes a difference in how the finished installation looks in the daylight. Our LED light strips come in two versions to match the surface the strip will be attached to. If you have a light colored truck you will probably want to order the WHITE PCB light strip. If you have a dark colored truck, you will probably want to order the BLACK PCB light strip.
