Zizindikiro za mayendedwe
Pakadali pano, mababu a incandescent akusinthidwa ndi ma diode otulutsa kuwala kwa LED. Zimagwira ntchito bwino komanso zimawunikira mwachangu kuposa mababu achikhalidwe.

Ma LED ndiwopambana pakuwunikira kwamagalimoto, monganso ma waya amagetsi kumayambiriro kwa zaka za zana la 20. Nyali poyamba zinkagwiritsidwa ntchito pa nyali zakutsogolo ndi zam'mbuyo. Kusintha kolowera kudawonetsedwa ndi ma levers otsetsereka omwe adayambitsidwa mu XNUMXs.
Pamene magalimoto m’mizinda anawonjezereka kwambiri m’zaka za m’ma 20, malamulo anaperekedwa m’maiko osiyanasiyana kuti aletse chipwirikiti cha pamsewu. Ku Germany, dalaivala anafunika kusonyeza kuti akufuna kusintha njira n’kuthyoka, kuti magalimoto amene ali kumbuyo achitepo kanthu mwamsanga. Ku Poland, njira zoyambira kukhazikitsa malamulo apamsewu zidawonekera mu 1921, pomwe malamulo oyendetsera magalimoto pamsewu wapagulu adaperekedwa.
Zizindikiro zotembenuka zatsimikizira kukhala zothandiza kwambiri potsatira malamulo apamsewu ndipo, koposa zonse, popewa kugundana kwambiri. Pambuyo kukanikiza batani lolingana, maginito amagetsi adatulutsa chowongolera chowongolera pafupifupi 20 cm kuchokera panyumba, kuwonetsa chikhumbo chofuna kusintha. Pambuyo pake, cholozeracho chidawunikira, zomwe zidapangitsa kuti chiwoneke bwino.
Opanga magalimoto amagwiritsa ntchito zida zapashelu zomwe zimapangidwa ndi anthu ena. Ku Germany, chizindikiro chotembenuka kuchokera ku Bosch, chomwe chidayambitsidwa pamsika mu 1928, chidadziwika; ku USA, makampani a Delco anali otchuka. Zizindikiro zowongolera ma elekitiroma zidangosinthidwa ndi ma siginecha omwe amadziwika mpaka pano m'ma 50s.
