Illumination integrated into the air intake system of Peterbilt trucks provides both aesthetic enhancement and increased visibility. These lights, often utilizing LED technology, are typically mounted within or around the air cleaner housing, serving as a distinctive visual element. For example, aftermarket kits allow customization of the color and intensity of the light emitted.
The integration of these lights contributes to improved safety, particularly during nighttime operation, by increasing the truck’s conspicuity. Furthermore, these lighting additions can reflect the operator’s or fleet’s branding and personalize the vehicle. Historically, the use of auxiliary lighting on heavy-duty trucks has evolved from purely functional applications to include elements of customization and visual appeal.
