Secret Sign

Perspex^® Cell Cast Secret Sign

Perspex^® Secret Sign is a specially developed signage sheet which looks black in daylight and white, red, green or blue when illuminated at night.

Perspex^® Secret Sign is ideal for use in self-contained units for “secret sign” constructions whose purpose is to display a message only when illuminated. Used in banks, shops, airports and car-parks, with Perspex^® Secret Sign you can create eye-catching signs – either to advertise a brand name with six foot high letters changing colour at night, or to display a clear instruction at the flick of a switch.

Thanks to its excellent and guaranteed weather performance and durability, Perspex^® Secret Sign is ideal for both indoor and outdoor signage, day and night!
