International ProStar Frame Light Bars-Panels

Frequently Asked Questions About International ProStar Frame Light Bars-Panels

What exactly are frame light bars and filler panels, and what do they do?

These are the panels and light bar assemblies that mount along the truck's frame rail, typically between the cab and fuel tank or behind the fairing area on an International ProStar. They close off the open gap along the frame, giving the truck a cleaner, finished look while also housing marker or accent lighting. They are primarily a cosmetic and trim component, though many include integrated lighting for visibility.

Will this fit my specific ProStar model year and configuration?

Frame panel fitment on the ProStar can vary by model year, cab style, and whether your truck has a fuel tank or air tank in that location, since panel length and mounting hole placement are matched to those dimensions. Always check the listed fitment details or measure your existing panel or opening before ordering, and reach out to our sales team with your VIN or truck specs if you are unsure.

What material and finish options are available?

These panels are commonly offered in stainless steel or aluminum, with finishes ranging from polished or brushed stainless to painted or plain aluminum. Stainless tends to hold up well against corrosion and is easier to keep looking clean, while aluminum is lighter weight. Choose based on how much shine and maintenance you want versus weight and budget.

Do the light bar versions come pre-wired, and are the lights DOT compliant?

Most light bar panels come with the lights already mounted in the panel, but you will still need to run wiring to your truck's harness and confirm bulb or LED type matches your electrical setup. If the lights are used as required marker or clearance lights, make sure the specific lights included meet DOT/FMVSS 108 requirements for color, placement, and visibility, since not every accent light bar is built to serve as a legal marker light.

How difficult is installation, and what will I need?

Installation is generally straightforward and can often be done with basic hand tools, since most panels bolt into existing frame holes or brackets. If the panel includes lighting, you will also need basic wiring tools and possibly connectors to tie into your existing harness. Some fitments may require minor drilling if hole patterns do not line up exactly, so it helps to compare the new panel against your old one before starting the install.
