Designed specifically for Kenworth T680 (2021), this LED headlight assembly is engineered to match factory wiring for true plug-and-play installation, requiring no drilling or modifications for a quick, clean, and hassle-free replacement. DOT and SAE approved for on-road use, it features an IP67-rated sealed housing that provides reliable protection against water, dust, and harsh weather conditions. The scratch-resistant, UV-protected polycarbonate lens helps prevent yellowing and aging over time, while the sealed rear cover effectively blocks moisture intrusion and reduces vibration-related noise during operation. Upgraded with a professional-grade projector lens and powered by premium CREE LED chips, this headlight delivers a precisely controlled beam pattern with a sharp cutoff, reducing glare and stray light while improving forward road penetration for enhanced visibility without blinding oncoming traffic. The all-in-one integrated design combines high beam, low beam, turn signal, and DRL into a single assembly, providing stable brightness, fast illumination response, and long-lasting performance. Built-in rear beam adjusters allow easy vertical and horizontal alignment, enabling fine-tuned light output for optimal road coverage, improved driving safety, and enhanced comfort.
