An online series of technical courses is part of a Truck-Lite Training Institute  recently begun by the lighting products manufacturer. This program offers web-based lessons for distributors, technicians and fleet personnel who sell, use and maintain equipment with Truck-Lite products.

TTI consists of training modules focused on product knowledge, diagnostics, systems functionality and repairs, Truck-Lite said. A Lighting and Harness module is the first to launch, and includes these courses:
