Kenworth T800 Frame Light Bars & Filler Panels

Frequently Asked Questions About Kenworth T800 Frame Light Bars & Filler Panels

What are frame light bars and filler panels used for on a Kenworth T800?

Frame light bars mount along the truck's frame rail, typically between the cab and rear wheels or near the fuel tanks, and hold marker, turn signal, or accent lighting. Filler panels are the flat metal or plastic pieces that cover the gap between the frame rail and other components, giving the truck a finished, streamlined look while also helping to keep debris and road spray away from wiring and mounting hardware.

Will these light bars and filler panels fit my specific T800 configuration?

Fit can vary based on frame rail height, wheelbase, fuel tank size, and whether your truck has a factory or aftermarket setup. Because the T800 was built in several configurations over the years, we recommend checking the listed specifications and measurements for each part against your truck before ordering. If you are unsure, having your VIN or frame rail dimensions on hand will help you or our team confirm the right fit.

What materials and finishes are available?

Most frame light bars and filler panels are available in stainless steel or aluminum, with finish options such as polished, brushed, or painted to match your truck. Stainless steel offers strong corrosion resistance for trucks that see harsh weather or road salt, while aluminum is lighter weight. The right choice usually comes down to your budget and how much shine or low-maintenance finish you prefer.

Do these come pre-drilled for lights, and are the lights included?

Many light bars come pre-drilled with mounting holes sized for standard round or oval lights, but the lights themselves are often sold separately unless the listing specifically states they are included. Filler panels may be plain or pre-drilled depending on the design, so check the product description to see whether you will need to drill your own holes or purchase lights separately.

Is installation something I can do myself, or should I have a shop handle it?

Installation difficulty depends on the specific part and whether it is a direct bolt-on replacement or requires drilling and wiring. Bolt-on filler panels and pre-drilled light bars are generally straightforward for someone comfortable with basic hand tools, while custom fitment or wiring in new lights may be easier with the help of a shop, especially if you want to ensure a clean, weather-tight installation.
