Ingxenye ekhombisayo yeivesti ekhanyayoyenziwe ubuchwepheshe obuthuthukisiwe bokugxila kanye nokucubungula ngemuva kokusebenzisa i-micro-diamond crystal lattice ukukhiqiza i-refraction kanye ne-high refractive index glass beads retro-reflective isimiso.Ingabonisa ukukhanya okukude okuqondile emuva endaweni ekhanyayo, futhi inokusebenza okuhle kwe-retroreflective optical kungakhathaliseki ukuthi kusemini noma ebusuku.Ikakhulukazi ebusuku, ingabonisa ukubonakala okuphezulu okufanayo nasemini.Izimpahla zokuphepha ezenziwe ngale nto ebonisa ukukhanya okuphezulu zingabonwa kalula abashayeli basebusuku kungakhathaliseki ukuthi umuntu ozigqokile usendaweni eyihlane noma ngaphansi kokuphazamiseka kokukhanya noma ukukhanya okuhlakazekile.
