Giving your Peterbilt 379, 388 or 389 a cohesive blend of style and lighting functionality is easier with 4-inch standard wrap cab panels that come with built-in light options. These chrome-plated stainless steel panels are designed to fit the cab side of the cited models (including 378, 379, 388 and 389, plus 389 Glider versions) and are sold as matched driver and passenger pairs with a range of lighting configurations-such as 14 two-inch round amber lights, multiple bullseye lights, elite or slotted patterns, and other cutout layouts spaced for common marker lights. Made in the USA as high-quality aftermarket (non-OEM) parts, they include a warranty against defects in workmanship and materials from the date of purchase and resist corrosion while adding a polished look to your truck's exterior. Because these panels ship directly from the manufacturer, they may arrive separately from other order items, so plan installation accordingly. Before buying, confirm that the light layout and fitment match your specific Peterbilt model year to ensure proper compatibility.
