Monga nyali yabwino yamchira, iyenera kukhala ndi izi:
(1) Kuwala kowala kwambiri komanso kufalikira kwamphamvu kwamphamvu;
(2) Kuwala kowala kowala nthawi yakutsogolo;
(3) Moyo wautali, kukonza kwaulere, kugwiritsa ntchito mphamvu zochepa;
(4) Kukhazikika kwamphamvu kwa switch;
(5) Kugwedezeka kwabwino komanso kukana kwamphamvu.
Pakadali pano, zowunikira zomwe zimagwiritsidwa ntchito pamagetsi amchira wagalimoto ndi nyali za incandescent. Kuphatikiza apo, magwero ena atsopano owunikira atuluka, monga ma light emitting diode (LED) ndi magetsi a neon.
