Exhaust Stack and Road Tractor Exhaust Pipe

[Category : - DESIGN PATENTS]
[Viewed 97 times]

This patent illuminates the exhaust on tractor trailers. This creates many benefits; most notably visibility and safety. It also greatly enhances the appearance of the semi tractor, giving it a unique lighted exhaust.

An exhaust stack is provided having an exhaust tube, an outer casing, a light, electrical wiring, and insulating material. The outer casing defines an interior in which the exhaust tube extends. The light is supported by the outer casing. The electrical wiring extends along an inner surface of the outer casing and is coupled to the light to supply power to the light. The insulating material is disposed within the interior of the outer casing between the exhaust tube and the electrical wiring.
