Cishe usuqaphele kakade ukuthi eziningi zakudala zesi-French (nangaphezulu) zisebenzisa izibani zangaphambili eziphuzi esikhundleni sokukhanya okumhlophe/okuphuzi. Futhi ngokuphambene nalokho ongase ukucabange, akuzona izizathu zobuhle.
Indaba ithi, njengamalambu aphuzi ahlukanisa izimoto zamasosha aseFrance kwezaseJalimane, uhulumeni waseFrance naye wayefuna ukuhlukanisa izimoto zabo emgwaqeni - okungelona iqiniso ngokuphelele. Ukuze sithole isizathu sangempela kufanele sibuyele emuva kuma-1930s ekhulwini leminyaka elidlule.
NgoNovemba 1936, kwaqala ukusebenza umthetho eFrance owawudinga ukuthi zonke izimoto zifakwe amalambu akhipha ukukhanya okuphuzi - "okuphuzi okukhethekile".
Kungani amalambu aphuzi?
Isizathu sasilula: ngokocwaningo lwe-Académie des Sciences, lokhu kukhanya kubangele ukukhanya okuncane kunokukhanya okumhlophe/okuphuzi, ikakhulukazi ezimweni zezulu ezingathandeki ukushayela (imvula noma inkungu).
Kusukela ngonyaka olandelayo, zonke izimoto ezibhaliswe eFrance - ngisho nezingenisiwe - zaqala ukusebenzisa amalambu aphuzi.
Amalambu aphuzi abesebenza kahle kakhulu futhi bekuhlale kuncanyelwa ukushayela esimweni sezulu esingesihle njengenkungu noma imvula.
Imfihlo isendleleni iso lomuntu elicubungula ngayo izinhlobo ezahlukene zokukhanya. Okumhlophe kuhlanganisa yonke imibala, futhi okuluhlaza okwesibhakabhaka, kwe-indigo kanye no-violet yileyo enobude obufushane begagasi. Ngakho-ke, yibo okunzima kakhulu ukucubungula, ngaphezu kokubangela ukukhanya okwengeziwe, okuholela ekukhazimuleni.
Ukususa la mathoni sithola ukukhanya okuphuzi, okuthi, ngokushuba okufanayo, kube nokukhanya okuncane, ngaleyo ndlela kube lula umsebenzi wamehlo ethu.

Ngakolunye uhlangothi, izifundo eziningana engxenyeni yesibili yekhulu lama-20 - ikakhulukazi ucwaningo olwenziwa eNetherlands ngo-1976 - lwaphetha ngokuthi ekusebenzeni kwakungekho umehluko omkhulu ekubonakaleni phakathi kwezinhlobo ezimbili zokukhanya. Kutholwe ukuthi ukuqina kwe-yellow light beam bekuphansi futhi lokhu kube nomthelela emuzweni wokucwebezela okuncane ohlangothini lwabashayeli, futhi hhayi ngempela ukubonakala okungcono.
Iqiniso liwukuthi ukukhanya kwezimoto ngaleso sikhathi kwakungadumile, kungakhathaliseki ukuthi ukukhanya kwakumhlophe noma kuphuzi. Njengakho konke okunye, ukukhanyisa kwavela ngokuhamba kweminyaka futhi, icindezelwa yi-European Union, eyayifuna ukumisa umthetho, iFrance yaqala ukwamukela izibani ezimhlophe ngo-1993 esikhundleni sokukhetha okuphuzi, ilandela isibonelo samanye amazwe aseYurophu .
Namuhla, amalambu aphuzi avaliwe eFrance, ngaphandle kwezimoto ezabhaliswa ngaphambi kuka-1993 noma uma kungamalambu enkungu nje. Futhi kuma-GT eLe Mans...
