Pambuyo pa zaka makumi ambiri za chitukuko cha ukadaulo, mphamvu yowala ya LED yakhala ikukwera kwambiri. Chifukwa cha monochromaticity yake yabwino komanso mawonekedwe ake ochepa, imatha kutulutsa kuwala kowoneka bwino popanda kusefa. Ilinso ndi ubwino wowala kwambiri, kugwiritsa ntchito mphamvu zochepa, moyo wautali, kuyambitsa mwachangu, ndi zina zotero. Itha kukonzedwa kwa zaka zambiri, zomwe zimachepetsa kwambiri ndalama zokonzera. Ndi malonda a LED yowala kwambiri mumitundu yofiira, yachikasu, yobiriwira ndi ina, pang'onopang'ono LED yasintha nyali yachikhalidwe ya incandescent kukhala nyali ya chizindikiro cha magalimoto.
Pakadali pano, magetsi amphamvu kwambiri a LED sagwiritsidwa ntchito pazinthu zotsika mtengo monga magetsi a magalimoto, magetsi, magetsi a LCD, magetsi a mumsewu a LED, komanso amatha kupeza phindu lalikulu. Komabe, chifukwa cha kubwera kwa magetsi akale a magalimoto ndi magetsi osakhwima a LED m'zaka zam'mbuyomu, magetsi atsopano a LED okhala ndi mitundu itatu agwiritsidwa ntchito kwambiri. Ndipotu, mtengo wa magetsi athunthu a LED okhala ndi ntchito zabwino komanso khalidwe labwino ndi wokwera mtengo kwambiri. Komabe, chifukwa cha ntchito yofunika ya magetsi a magalimoto m'mizinda, magetsi ambiri a magalimoto amafunika kusinthidwa chaka chilichonse, zomwe zimapangitsa kuti msika ukhale waukulu. Kupatula apo, phindu lalikulu limathandizanso pakukula kwa makampani opanga ndi kupanga ma LED, ndipo lidzapangitsanso kuti makampani onse opanga ma LED azisangalala ndi ntchito yabwino.
Zinthu za LED zomwe zimagwiritsidwa ntchito poyendetsa magalimoto makamaka zimaphatikizapo chizindikiro chofiira, chobiriwira ndi chachikasu, chiwonetsero cha nthawi ya digito, chizindikiro cha muvi, ndi zina zotero. Chogulitsachi chimafuna kuwala kwamphamvu kwambiri masana kuti chikhale chowala, ndipo kuwala kuyenera kuchepetsedwa usiku kuti chisawonekere kuwala. Gwero la kuwala kwa nyali yolamula ya chizindikiro cha magalimoto cha LED limapangidwa ndi ma LED angapo. Popanga gwero lofunikira la kuwala, malo angapo ofunikira ayenera kuganiziridwa, ndipo pali zofunikira zina pakuyika kwa LED. Ngati kukhazikitsa sikukugwirizana, kudzakhudza kufanana kwa mphamvu yowala ya pamwamba pa kuwala. Chifukwa chake, momwe mungapewere cholakwika ichi chiyenera kuganiziridwa mu kapangidwe kake. Ngati kapangidwe ka kuwala ndi kosavuta kwambiri, kugawa kuwala kwa nyali ya chizindikiro kumatsimikiziridwa makamaka ndi mawonekedwe a LED yokha, Kenako zofunikira pakugawa kuwala ndi kukhazikitsa kwa LED yokha ndizokhwima, apo ayi izi zidzakhala zodziwikiratu.
Ma LED traffic lights ndi osiyana ndi ma signal light ena (monga ma headlights a magalimoto) pa kugawa kwa kuwala, ngakhale kuti alinso ndi zofunikira pa kugawa kwa kuwala kwamphamvu. Zofunikira za ma headlights a magalimoto pamzere wodula kuwala ndi zovuta kwambiri. Bola ngati kuwala kokwanira kwaperekedwa pamalo oyenera pakupanga ma headlights a magalimoto, osaganizira komwe kuwala kumatulutsidwa, wopanga amatha kupanga malo ogawa kuwala kwa lens m'zigawo zazing'ono ndi ma subblocks, koma nyali ya traffic signal iyeneranso kuganizira kufanana kwa kuwala kwa malo onse otulutsa kuwala. Iyenera kukwaniritsa zofunikira kuti poyang'ana pamwamba potulutsa kuwala kwa chizindikiro kuchokera kumalo aliwonse ogwirira ntchito omwe nyali ya signal imagwiritsidwa ntchito, mawonekedwe a chizindikiro ayenera kukhala omveka bwino ndipo mawonekedwe ake ayenera kukhala ofanana. Ngakhale nyali ya incandescent ndi nyali ya halogen tungsten light source signal source ili ndi kuwala kokhazikika komanso kofanana, ili ndi zolakwika monga kugwiritsa ntchito mphamvu zambiri, moyo wotsika wa ntchito, zosavuta kupanga chizindikiro cha phantom, komanso ma color chips ndi osavuta kuzimitsa. Ngati tingachepetse kuwala kwa LED komwe sikunazime ndikuchepetsa kuchepa kwa kuwala, kugwiritsa ntchito kuwala kwambiri komanso kugwiritsa ntchito mphamvu zochepa kwa LED mu nyali ya chizindikiro kudzabweretsa kusintha kwakukulu pazinthu za nyali ya chizindikiro.
