As the transportation industry pivots towards safer and more sustainable mobility solutions, the role of advanced surface technologies is becoming increasingly critical. This paper presents a novel application of electroluminescent (EL) coating systems in heavy-duty trucks, exploring to enhance safety and environmental impact through lightweight, energy-efficient lighting integration. EL coatings, capable of emitting light uniformly across painted surfaces when electrically activated, offer a transformative alternative to conventional lighting systems and reflective materials. In the context of heavy-duty trucks, these systems can significantly improve visibility under low-light and adverse weather conditions, thereby reducing the risk of road accidents. Furthermore, illumination achieved without bulky fixtures and without interface gaps contributes to aerodynamic efficiency, fuel economy and reducing carbon emissions. use of this coating system, can optimize tooled up plastic part and sub-assemblies specially to those parts we use for indication, marking, & lighting during dark This paper identifies and evaluates specific use cases where EL coatings can deliver substantial benefits: for example, Lighting systems, Perimeter Lighting, Ingress/degrees illumination with Integrated Safety Features, Emergency and Breakdown Visibility & Trucking illumination accessories. Accentuate brand specific, Technology & design features over a truck This study examines the working principle, technical feasibility of deploying EL coatings on large commercial vehicle surfaces. It includes a comprehensive assessment on system architecture, energy requirements, integration considerations, and potential materials and application methods suitable for automotive-grade use. The paper further discusses the integration challenges, lifecycle considerations, and implications for vehicle design and regulatory compliance. By positioning light as a functional, safety-critical component of the vehicle's surface, this research proposes a forward-looking approach to sustainable vehicle design. It aims to contribute to the automotive research community's efforts in enabling intelligent, safer, and greener transportation systems.
