DMS Retrofit Upgrade Program – LED Modernization Solution
Industry Applications
The DMS Retrofit Upgrade Program is ideal for DOT agencies and roadway authorities seeking to extend the life of legacy overhead or arterial dynamic message signs without full system replacement.
Product Overview
AMSIG’s DMS Retrofit Upgrade Program (DRUP) replaces legacy non-LED display technologies with modern, high-performance LED modules and NTCIP-compliant controllers. Designed and manufactured in the USA, AMSIG retrofit systems benefit from decades of experience in mobile and overhead DMS deployments. Thousands of AMSIG dynamic message signs operate across North America and Europe, enduring demanding environmental conditions. The retrofit program includes a no-charge, on-site pre-quotation evaluation and a simplified One Sign, One Price approach, including installation of a new NTCIP-compliant controller. This cost-effective modernization strategy improves visual performance, energy efficiency, and long-term reliability while reducing lifecycle costs.
