Freightliner FLC120 Frame Light Bars-Filler Panels

Frequently Asked Questions About Freightliner FLC120 Frame Light Bars-Filler Panels

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

These are the flat or contoured panels that mount along the frame rail between the bumper and the front axle or fender area on the Freightliner FLC120. They close the gap along the frame, giving the front end a finished look while also providing a mounting surface for auxiliary lighting such as marker lights, fog lights, or LED strips.

Will this panel fit my FLC120 without modification?

Fitment can vary depending on the model year and configuration of your FLC120, including bumper style and frame width. We recommend checking the listed specifications and comparing them to your truck's existing panel or frame dimensions before ordering. If you are unsure, measuring your current filler panel or reaching out to our team with your truck's details will help confirm the right fit.

What materials are these filler panels made from, and how do they hold up?

Filler panels in this category are typically offered in steel or aluminum, and sometimes stainless steel. Steel panels are often finished with a durable coating or left ready for paint to match your truck, while aluminum and stainless options offer added corrosion resistance. Choosing the right material largely comes down to your budget and whether you prefer a painted match or a bare metal look.

Do these panels come pre-drilled for lights, and can I add my own?

Many filler panels are pre-drilled or punched for common light configurations, which simplifies installation if you are using standard replacement lights. If a panel does not come pre-drilled, or your light setup differs, you can typically drill it yourself, though we suggest planning hole placement carefully to keep wiring routing clean and avoid weakening the panel.

How difficult is it to install a frame light bar-filler panel myself?

Installation is generally straightforward and can be done with basic hand tools, since these panels bolt onto existing frame mounting points. The job usually involves removing the old panel, transferring or wiring any lights, and bolting the new panel into place. Having a second person to help align and hold the panel during installation makes the process easier, especially on larger panels.
