Inqwelwana yegalufa yindlela ebhetyebhetye kakhulu, eyohlukeneyo kwaye esebenzayo yothutho lwempahla, edla ngokusetyenziselwa ukuthutha iimpahla. Ibonakala ngokuguquguquka kokutshintsha okanye ukulungelelanisa i-hopper yempahla ngokweemfuno, ukwenzela ukuba kube lula ukuthuthwa kweentlobo ezahlukeneyo zeempahla. Inqwelo yempahla ihlala ixhotyiswe ngezibane ezahlukeneyo zokhuseleko, ezibandakanya:
1. Izibane ezidityanisiweyo zangaphambili ze-LED (i-beam ephantsi, i-beam ephezulu, isignali yokujika, ukukhanya kwemini, ukukhanya kwendawo)
2. Ukukhanya kwe-LED ngasemva komsila (ukukhanya kwebrake, ukukhanya kwendawo, umqondiso wokujika)
