Xa imeko yokukhanya kwendlela inganelanga, ukukhanya kwekona kudlala indima ethile ekukhanyiseni okuncedisayo kwaye kubonelela ngesiqinisekiso sokhuseleko lokuqhuba. Olu hlobo lwezibane, ngakumbi kwimeko yendlela, iimeko zokukhanyisa azikho kwindawo eyaneleyo, zidlala indima ethile ekukhanyiseni okuncedisayo.
Umgangatho kunye nokusebenza kwezibane zeemoto kunye nezibane kubaluleke kakhulu kukhuseleko lwezithuthi, ilizwe lethu lenze imigangatho yesizwe ngokwemigangatho ye-ECE yaseYurophu ngo-1984, kwaye ukuchongwa kokusebenza kokusasazwa kokukhanya kwezibane yenye yezona zibalulekileyo phakathi kwazo.
