Kenworth W900A Frame Light Bars & Filler Panels

Frequently Asked Questions About Kenworth W900A Frame Light Bars & Filler Panels

What are frame light bars and filler panels used for on a Kenworth W900A?

Frame light bars and filler panels mount along the truck's frame rail, typically between the cab and rear wheels or near the fuel tanks, to close gaps in the chassis while adding auxiliary and marker lighting. They serve a dual purpose: improving the truck's appearance by giving it a clean, finished look along the frame, and providing additional lighting for visibility and style.

Will a frame light bar or filler panel fit my specific W900A configuration?

Fit depends on your truck's wheelbase, frame rail spacing, and fuel tank size and placement, since these panels are designed to fill the specific gap on a given chassis setup. Before purchasing, measure the gap you're filling and compare it to the panel's listed dimensions, and check whether the panel is designed for a particular fuel tank diameter or frame configuration.

What material and finish options are available?

These panels and light bars are commonly available in stainless steel or aluminum, with finishes ranging from polished and brushed to diamond plate textures. Stainless steel generally offers better corrosion resistance and a longer-lasting shine, while aluminum is lighter. Choose a finish that matches the rest of your truck's trim for a consistent look.

How are frame light bars and filler panels installed?

Most panels bolt or clamp directly to the frame rail using existing mounting holes or brackets included with the part. If the panel includes lighting, you'll also need to run and connect wiring to your truck's electrical system, which may involve splicing into existing harnesses or adding a separate circuit. Basic hand tools are typically sufficient, but electrical work should be done carefully to avoid shorts or unintended draws on your battery.

Are the lights on these panels legal for road use, and what type of lighting do they use?

Most frame light bars use LED marker or auxiliary lights, which are energy efficient and long-lasting. Whether they're legal for your specific use depends on light color, placement, and your state or provincial regulations, since amber, red, and white lights each have different permitted locations and functions. Always check that the lighting on any panel you install complies with DOT requirements and local laws before hitting the road.
