MULLION EN 471

Thanks to high visibility warning clothing, the wearer will be seen when visibility is low :

• during the day, because of the fluorescent background material
(fluorescence due to presence of UV light).

• during the night, when the retroreflective stripes reflect the oncoming headlights.
