Custom Underglow Light Setups on Semi Trucks

28th Nov 2025

If you're looking for a way to dramatically enhance the look and presence of your semi truck at night, then you can't go wrong with installing some undercarriage chicken lights.

Need inspiration? Here are some of the best-looking nighttime rigs that utilize under glow lighting to their advantage!

These under glow lighting styles ADD to the overall theme of each truck, accentuating or complementing the existing primary lighting style pattern.

Why Underglow Lighting is So Popular at Truck Shows

Reason #1: This subtle lighting setup accentuates the polished reflective tone of your exterior chrome, from the side panels to the step box, during dusk or nighttime runs.

Reason #2: It adds an entirely different vibe to your truck, giving it a fuller presence.

Reason #3: You can place underglow lights just about anywhere on the truck, accentuating the fuel tank or step boxes, rear-T bar or even the cross-section panel frame.

When it comes to commercial semi truck lighting, customization truly is the name of the game.

You can choose the bulb type, housing, and multi-lighting setups that can switch colors from legal rear-facing red and forward-facing amber to whatever color hue you want: purple, white, green, blue, or hot pink...your choice.

Try 3-4 Wire Setups for Color-Changing Lighting Systems

You can install multi-colored 2-inch marker lights that are wired to change with a simple flick of a switch.

Place them in multiple areas of your truck, like the rear-T lightbar or underbody panels nestled beneath your frame-chassis.

Custom Lighting Setups That Don't Need Underglow Lights

Admittedly, underglow lights are cool, but some rigs obtain the same overall effect from carefully-placing accent LED strip lights and cab/marker lights.

You can set these just about anywhere: the bumper, side panels, step box, fuel tank, or on drilled-in brackets placed just below the length of the frame.

Installing the right type of surround lighting can make your truck's mirror-polished chrome "pop" with vibrancy at dawn, dusk, or nighttime.

Adding underbody lighting just adds a bit more presence.

LED Strip Lighting vs Underglow Lights

LED strip lights are an easier, and temporary, way of achieving a similar result to underbody lighting. The strips aren't going to have the same intense glow as underbody cab lights.

Lighting strips are a specialty lighting can be added to the interior of your cab as well as the exterior.

Some LED light strips are cuttable, so you can adjust their length to fit your application as needed. Other products feature a dual-tone light display for even more personalization.

Some come with an in-built adhesive backing, while others require mounting pieces to secure.

Hopefully this gives you some inspiration, and good information to fuel your next aftermarket underglow lighting purchase, whether it's a full-length underbody lighting kit, or some budget-friendly strip lighting sets.
