1. Ngenxa yokuba khona kobuhlalu bengilazi ebusweni bayo obukhanyisa amalambu ezimoto, izithuthuthu namabhayisikili, ubuhlalu beglasi bokumaka umgwaqo busetshenziselwa ukuqondisa abasebenzisi bomgwaqo ebumnyameni. Uma ushayela ebusuku, isibani semoto semoto sibuyiselwa esweni lomshayeli, ukuze umshayeli abone umgwaqo phambili kahle futhi ashayele ngokuphepha. Ukuze ubuhlalu bubuyisele emuva ukukhanya, izakhiwo ezimbili ziyadingeka: ukwenza izinto obala kanye nokuzungeza. Ubuhlalu obenziwe ngengilazi bunazo zombili lezi zakhiwo.Isidingo sokubekwa obala kanye nokuzungeza kungabonakala kubalulekile uma ulandela indlela yokukhanya njengoba ingena ebuhlalu obugxunyekwe ukumakwa komgwaqo okusetshenzisiwe. Ubuhlalu beglasi kufanele bube sobala ukuze ukukhanya kudlule kungene kuphume emkhakheni. Njengoba i-light ray ingena ebuhlalu iphinda ikhonjwe yindawo eyindilinga yobuhlalu lapho ifakwe khona kupende. Ukukhanya okushaya ngemuva kobuso obuhlotshiswe ngopende kubonakala ebusweni bepende, kanye nengxenyana encane yokukhanya ebuyela emuva emthonjeni wokukhanyisa.

Ukuze kuqinisekiswe izinga eliphezulu lokubonakala kuzo zonke izimo zezulu, u-Olan usungule amabanga obuhlalu beglasi ahlukene afanele uhlobo ngalunye lwesicelo.

Kukhona amamaki amabili ajwayelekile ngesikhathi sokufaka isicelo: I-Premix neDrop-on

I-Premix (Intermix), yayijwayele ukuhlanganiswa nopende ngaphambi kokuhluba umgwaqo. Njengoba izingqimba zokupenda zigqoka, ubuhlalu buvezwa obenza kubonakale ngcono ukumakwa komgwaqo.

IDrop-On, ebijwayele ukwehliswa ebusweni bopende obusanda kufakwa emgwaqeni ukuze inikeze ukubonakala okuthuthukile ngokushesha kubashayeli basebusuku.

Ukubonakala emini kanye nasebusuku ezimeni ezahlukahlukene zezulu, ukusebenza kwe-anti-skid, ukumelana nokugqoka nokuqina yizimpawu ezibalulekile zokumakwa komgwaqo okuhle. U-Olan ukhiqiza ubuhlalu bezingilazi zazo zonke izinhlobo zemikhiqizo yokumaka imigwaqo njengopende bokuncibilika okusetshenziswayo namanzi, ama-thermoplastics nezinhlelo zezinto ezi-2.
