Frequently Asked Questions About Peterbilt 567/579 Frame Light Bars & Filler Panels

What exactly is a frame light bar or filler panel?

These components fill the open space along the frame rails or below the bumper on Peterbilt 567 and 579 trucks, giving the front end a finished, factory-style look. Many versions include integrated LED lighting, such as marker lights or auxiliary lights, combining a clean appearance with added visibility on the road.

Will this panel fit my specific Peterbilt model and year?

Frame light bars and filler panels are typically designed to match the frame width and mounting points of either the 567 or 579 model, so it is important to confirm which chassis your truck uses before ordering. If you are unsure, check your truck's VIN or existing frame configuration, or contact our team with your truck's details so we can confirm proper fit.

What material and finish options are available?

These panels are commonly made from stainless steel or durable powder-coated steel to hold up under road debris, weather, and daily wear. Finish options often include polished stainless or painted-to-match black finishes, so you can choose based on the rest of your truck's trim and your maintenance preferences.

How difficult is installation, and can I do it myself?

Most frame light bars and filler panels are designed to bolt on using existing mounting holes or brackets, making them a reasonable DIY project for someone comfortable with basic hand tools. If your panel includes integrated lighting, you will also need to run and connect wiring to your truck's existing light circuits, so having basic electrical knowledge or a wiring diagram on hand is helpful.

If the panel has built-in lights, are they DOT compliant?

Lighting integrated into these panels is generally intended to supplement your truck's existing marker and clearance lights rather than replace required DOT lighting. Always verify that any added lights meet FMVSS 108 requirements for color, placement, and function, and make sure your truck's primary required lighting remains unobstructed and fully operational after installation.
