Ekuqaleni kwekhulu le-19, eDolobheni laseYork eCentral England, izingubo ezibomvu neziluhlaza zazimelela ubunikazi obuhlukene babesifazane. Phakathi kwazo, owesifazane ogqoke obomvu usho ukuthi ngishadile, kanti owesifazane ogqoke okuluhlaza akashadile. Kamuva, izingozi zenqola zazivame ukwenzeka phambi kwesakhiwo sephalamende eLondon, eNgilandi, ngakho abantu baphefumulelwa yizingubo ezibomvu neziluhlaza. Ngomhlaka-10 Disemba 1868, ilungu lokuqala lomndeni wesibani sesignali lazalelwa esigcawini sesakhiwo sephalamende eLondon. Isikhundla sesibani esaklanywa futhi sakhiqizwa yi-mechanic de Hart yaseBrithani ngaleso sikhathi sasiphakeme ngamamitha ayi-7, futhi sasilenga ngesibani semoto esibomvu nesiluhlaza - i-Green Lantern, okwakuyisibani sokuqala sesignali emgwaqweni wedolobha.
Phansi kwesibani, iphoyisa elinesigxobo eside ladonsa ibhande ukuze lishintshe umbala wesibani ngokuthanda kwalo. Kamuva, kwafakwa isibani segesi phakathi kwesibani sesignali, futhi kwakukhona izingcezu ezimbili zengilazi ebomvu neluhlaza phambi kwaso. Ngeshwa, isibani segesi, esasitholakala izinsuku ezingu-23 kuphela, saqhuma ngokuzumayo saphuma, sabulala iphoyisa elalisemsebenzini.
Kusukela ngaleso sikhathi, izibani zomgwaqo zedolobha ziye zavalwa. Kwaze kwaba ngo-1914 lapho iCleveland e-United States yahola ekuvuseleleni izibani zomgwaqo, kodwa kakade “yayisibani sesignali kagesi”. Kamuva, izibani zomgwaqo zaphinde zavela emadolobheni anjengeNew York neChicago.
Ngokuthuthuka kwezindlela ezahlukene zokuhamba kanye nezidingo zomyalo wethrafikhi, ukukhanya kokuqala kweqiniso okune-tricolor (izimpawu ezibomvu, eziphuzi neziluhlaza) kwazalwa ngo-1918. Kuyiprojektha enezinhlangothi ezine enemibala emithathu, efakwe embhoshongweni oseFifth Street eNew York City. Ngenxa yokuzalwa kwayo, ithrafikhi yasemadolobheni ithuthuke kakhulu.
Umsunguli wesibani sesignali esiphuzi nguHu ruding waseShayina. Enesifiso "sokusindisa izwe ngesayensi", waya e-United States ukuze ayofunda kabanzi futhi wasebenza njengesisebenzi seGeneral Electric Company yase-United States, lapho u-Edison, umsunguli omkhulu, wayengusihlalo. Ngolunye usuku, wema endaweni ematasa elinde isibani sesignali esiluhlaza. Lapho ebona isibani esibomvu futhi esezodlula, imoto ephendukayo yadlula inomsindo ovunguzayo, owamethusa ngokujuluka okubandayo. Lapho ebuyela endlini yokulala, wacabanga kaninginingi, futhi ekugcineni wacabanga ukwengeza isibani sesignali esiphuzi phakathi kwezibani ezibomvu neziluhlaza ukuze akhumbuze abantu ukuthi baqaphele ingozi. Isiphakamiso sakhe saqinisekiswa ngokushesha yizinhlangothi ezithintekayo. Ngakho-ke, izibani zesignali ezibomvu, eziphuzi neziluhlaza, njengomndeni wesignali ophelele, zisakazeke emhlabeni wonke emkhakheni wezokuthutha komhlaba, olwandle kanye nomoya.
Izibani zomgwaqo zokuqala eShayina zavela esivumelwaneni saseBrithani eShanghai ngo-1928. Kusukela ebhandeni lokuqala elibanjwe ngesandla kuya ekulawuleni kukagesi ngawo-1950, kusukela ekusetshenzisweni kokulawula ikhompyutha kuya ekuqapheni isikhathi se-elekthronikhi yesimanje, izibani zomgwaqo ziye zavuselelwa njalo, zathuthukiswa futhi zathuthukiswa kwezesayensi kanye nokwenza izinto ngokuzenzakalela.
