Peterbilt 362 Frame Light Bars & Filler Panels

Frequently Asked Questions About Peterbilt 362 Frame Light Bars & Filler Panels

What are frame light bars and filler panels used for on a Peterbilt 362?

Frame light bars and filler panels are mounted along the frame rail, typically between the cab and rear wheels or near the fuel tanks, to close gaps along the chassis while providing a mounting location for marker lights, clearance lights, or auxiliary lighting. They serve both a functional lighting purpose and a finishing purpose by giving the underside of the truck a cleaner, more complete look.

Will these light bars and filler panels fit my Peterbilt 362 without modification?

Fitment depends on your specific frame length, wheelbase, and existing mounting holes, since Peterbilt 362 trucks were built with different configurations over the years. Most panels are designed to bolt into existing holes or align with factory mounting points, but you should always compare measurements against your truck before ordering, and some trimming or drilling may be needed depending on your setup.

What materials and finishes are available for these panels?

These panels are commonly available in stainless steel or aluminum, with finish options such as polished, brushed, or diamond plate textures. Stainless steel tends to hold up well against corrosion and is easier to keep polished, while aluminum offers a lighter weight option. The right choice usually comes down to your budget and how much maintenance you're willing to put into keeping the finish looking new.

Do the light bars come pre-wired or with the lights included?

This varies by product, so it's important to check the specific listing details. Some light bars come with lights, grommets, and wiring already installed, while others are sold as blank panels with cutouts that require you to purchase and install lights separately. If you're replacing an existing light bar, matching the light spacing and hole pattern to your current wiring harness will make installation much simpler.

Do I need to worry about DOT compliance when adding or replacing these lights?

Yes, any marker or clearance lights mounted on the frame need to meet DOT requirements for color, placement, and visibility. If your filler panel or light bar includes lighting, verify that the light color and positioning align with DOT regulations for your truck's length and configuration. When in doubt, check with a qualified technician or reference FMVSS 108 guidelines before finalizing your installation.
