The illuminated, double-sided door seal is designed to enhance passenger orientation and safety by providing continuous light along the door edges. This light is visible both outside and inside the vehicle, improving accessibility for all passengers, including those with disabilities.

Constructed from translucent silicone, the seal offers increased tear strength and resistance to vandalism compared to EPDM. The light source is embedded and inaccessible, ensuring durability and safety. The product has a service life of up to 15 years, nearly double that of EPDM alternatives.

The system contributes to improved dwell time, with observed gains of up to 3 seconds per station on RER C (Paris), by by making door closures more visible and discourage passengers from boarding at the last second. The seal is compatible with both new and existing rolling stock and allows for quick installation. It is fully customizable in terms of color, pattern, and light intensity, with no constraints on length.
