Emva kwamashumi eminyaka yophuhliso lwetekhnoloji, ukusebenza kakuhle kwe-LED kuphuculwe kakhulu. Ngenxa yokuba i-monochromaticity yayo entle kunye ne-spectrum encinci, inokukhupha ukukhanya okubonakalayo okunemibala ngaphandle kokucoca. Ikwanazo neenzuzo zokukhanya okuphezulu, ukusetyenziswa kwamandla aphantsi, ubomi benkonzo ende, ukuqala ngokukhawuleza, njl. ingalungiswa iminyaka emininzi, nto leyo enciphisa kakhulu iindleko zokugcina. Ngokuthengiswa kwe-LED ekhanyayo ephezulu ngemibala ebomvu, emthubi, eluhlaza kunye neminye, i-LED iye yathatha indawo yesibane sendabuko se-incandescent njengesibane sesignali yendlela.
Okwangoku, i-LED enamandla aphezulu ayisetyenziswa kuphela kwiimveliso zexabiso eliphezulu ezifana nezibane zeemoto, izixhobo zokukhanyisa, izibane zangasemva ze-LCD, izibane zesitalato ze-LED, kodwa inokufumana inzuzo enkulu. Nangona kunjalo, ngokufika kokutshintshwa kwezibane zetrafikhi eziqhelekileyo zakudala kunye nezibane zesignali ze-LED ezingavuthwanga kwiminyaka edlulileyo, izibane zetrafikhi ze-LED ezinemibala emithathu ezikhanyayo ziye zakhuthazwa kakhulu kwaye zasetyenziswa. Enyanisweni, ixabiso leseti epheleleyo yezibane zetrafikhi ze-LED ezinemisebenzi egqibeleleyo kunye nomgangatho ophezulu libiza kakhulu. Nangona kunjalo, ngenxa yendima ebalulekileyo yezibane zetrafikhi kwitrafikhi yasezidolophini, inani elikhulu lezibane zetrafikhi kufuneka lihlaziywe minyaka le, nto leyo ekhokelela kwimarike enkulu. Emva kwayo yonke loo nto, inzuzo ephezulu ikwanceda ekuphuhlisweni kweenkampani zemveliso kunye noyilo lwe-LED, kwaye iya kuvelisa nokukhuthaza okuhle kulo lonke ishishini le-LED.
Iimveliso ze-LED ezisetyenziswa kwicandelo lezothutho ziquka ikakhulu uphawu olubomvu, oluhlaza okwesibhakabhaka nolutyheli, umboniso wexesha ledijithali, uphawu lwe-arrow, njl. Le mveliso ifuna ukukhanya okunamandla kakhulu emini ukuze kukhanye, kwaye ukukhanya kufuneka kuncitshiswe ebusuku ukuze kuthintelwe ukukhanya. Umthombo wokukhanya wesibane somyalelo wesignali yethrafikhi ye-LED wenziwe zii-LED ezininzi. Xa kuyilwa umthombo wokukhanya ofunekayo, kufuneka kuqwalaselwe iindawo ezininzi ezijolise kuko, kwaye kukho iimfuno ezithile zokufakelwa kwe-LED. Ukuba ukufakelwa akuhambelani, kuya kuchaphazela ukufana kwesiphumo sokukhanya somphezulu okhanyayo. Ke ngoko, indlela yokuphepha esi siphene kufuneka iqwalaselwe kuyilo. Ukuba uyilo lwe-optical lulula kakhulu, ukusasazwa kokukhanya kwesibane sesignali kuqinisekiswa kakhulu yimbono ye-LED ngokwayo, Emva koko iimfuno zokusasazwa kokukhanya kunye nokufakwa kwe-LED ngokwayo zingqongqo, kungenjalo le nto iya kuba sobala kakhulu.
Izibane zetrafikhi ze-LED zahlukile kwezinye izibane zesignali (ezifana neentloko zemoto) ekuhanjisweni kokukhanya, nangona zikwaneemfuno zokusasazwa kokukhanya okunamandla. Iimfuno zezibane zentloko zemoto kumgca wokunqunyulwa kokukhanya zingqongqo ngakumbi. Ukuba nje ukukhanya okwaneleyo kwabelwe indawo ehambelanayo kuyilo lweezibane zemoto, ngaphandle kokuqwalasela apho ukukhanya kukhutshwa khona, umyili unokuyila indawo yokusasazwa kokukhanya kwelensi kwiindawo ezincinci kunye neebhloko ezincinci, kodwa isibane sesignali yetrafikhi kufuneka siqwalasele ukufana kwesiphumo sokukhanya somphezulu wonke okhupha ukukhanya. Kufuneka sihlangabezane neemfuno zokuba xa sijonga umphezulu okhupha ukukhanya wesignali kuyo nayiphi na indawo yokusebenza esetyenziswa sisibane sesignali, ipateni yesignali kufuneka icace kwaye isiphumo sokubonakala kufuneka sifane. Nangona isibane se-incandescent kunye nesibane se-halogen tungsten isibane somthombo wesignali yokukhanya sinokukhanya okuzinzileyo nokufanayo, sineziphene ezifana nokusetyenziswa kwamandla aphezulu, ubomi obuphantsi benkonzo, kulula ukuvelisa isibonisi sesignali ye-phantom, kwaye iitships zemibala kulula ukuzicima. Ukuba singayinciphisa into yokuba ukukhanya kwe-LED kufiphele size sinciphise ukuncitshiswa kokukhanya, ukusetyenziswa kokukhanya okuphezulu kunye nokusetyenziswa kwamandla aphantsi kwe-LED kwisibane sesiginali ngokuqinisekileyo kuya kuzisa utshintsho olukhulu kwiimveliso zesibane sesiginali.
