\u0130ngiltere’nin Birmingham \u015fehrinde bulunan Oliver Lucas, 1910’da standart bir elektrikli araba kornas\u0131 icat etmi\u015ftir. Daha sonra\u00a0\u0130lk seri \u00fcretim elektrikli korna \u0130ngiltere’de United Motor Industries Ltd. taraf\u0131ndan Wagner Electric Motor Horn ad\u0131yla \u00fcretildi. 28 A\u011fustos 1906’da The Motor adl\u0131 dergide ilanlarla t\u00fcketicilere tan\u0131t\u0131ld\u0131.
