For Peterbilt 379, 388 and 389 trucks, a set of 4-inch cab panels with light options provides a polished stainless-steel exterior upgrade that combines durable trim with integrated amber lighting to boost both visibility and style. These panels are made in the USA from corrosion-resistant stainless steel and sold as matched driver and passenger pairs, with numerous factory-configured lighting layouts such as ten bullseye lights per side with 4-inch spacing, thirteen bullseye lights per side with 3-inch spacing, or other options including round 2-inch, slotted, elite, oval and elite mini lights spaced for symmetry and balanced illumination. Because they are high-quality aftermarket (non-OEM) parts, these cab panels offer a cost-effective solution for replacing worn trim or adding standout lighting without additional drilling, and they include a warranty against defects in workmanship and materials from the date of purchase. Panels ship directly from the manufacturer and may arrive separately from other items in your order, so coordinate delivery and installation accordingly. Before ordering, verify fitment for your specific Peterbilt model year to ensure the panel and lighting configuration match your rig.
