LLEPM (Low-Location Exit Path Markings)

Luminous Exit Path Markings – Lighting the Way to Safety

INPS has worked closely with many mass transit car builders and transit authorities to design, engineer and manufacture luminous egress systems that work both functionally and financially.

Our LLEPM (low-location exit path markings) products are manufactured using the highest quality materials in terms of durability and safety. They are suitable for new or existing rubber or carpet floor coverings. With other applications such as seats and walls.

LLEPM is mandatory on all passenger rolling stock related by the Federal Railroad Adminstration (FRA) and has become mandatory on all equipment operating under the self-regulating guidelines of American Public Transportation Association (APTA). It is part of the Emergency Preparedness Plans of each transit agency. To minimize cost and increase ease of installation, INPS has developed turnkey solutions that include egress signage and low-level emergency path illumination products.
