Zprvu se jednalo o ho\u0159\u00edc\u00ed pochodn\u011b, kter\u00e9 pozd\u011bji vytla\u010dily olejov\u00e9 lampy. Pokud bychom n\u011bkolik stalet\u00ed minuli a sko\u010dili a\u017e do stolet\u00ed devaten\u00e1ct\u00e9ho, na cestu by n\u00e1m posv\u00edtilo osv\u011btlen\u00ed plynov\u00e9.  Po m\u011bstech chodili p\u0159ed setm\u011bn\u00edm lamp\u00e1\u0159i, kte\u0159\u00ed pomoc\u00ed dlouh\u00e9 ty\u010de rozsv\u011bceli lampy. Stejnou obch\u016fzku konali pak r\u00e1no, kdy bylo pot\u0159eba op\u011bt pozhas\u00ednat. Elektrick\u00e9 osv\u011btlen\u00ed se dostalo ke slovu a\u017e na po\u010d\u00e1tku stolet\u00ed dvac\u00e1t\u00e9ho. P\u0159ed t\u00edm to byly sp\u00ed\u0161e ojedin\u011bl\u00e9 zkou\u0161ky. \u00dapln\u011b prvn\u00edm m\u011bstem, kter\u00e9 mohlo pozorovat elektrick\u00e9 osv\u011btlen\u00ed v praxi, byl roku 1887 Jind\u0159ich\u016fv Hradec. Jednalo se ale pouze o jedno n\u00e1m\u011bst\u00ed a p\u0159ilehlou ulici. Je\u0161t\u011b t\u00e9ho\u017e roku koupil P\u00edsek obloukov\u00e9 lampy a m\u011bsto se rozsv\u00edtilo cel\u00e9. Proto je jako prvn\u00ed uv\u00e1d\u011bn v\u011bt\u0161inou pr\u00e1v\u011b P\u00edsek a na Jind\u0159ich\u016fv Hradec se nepr\u00e1vem zapom\u00edn\u00e1.   Typick\u00e9 \u017elut\u00e9 sv\u011btlo  Elektrifikace na\u0161ich m\u011bst byla tedy zah\u00e1jena, ale plynov\u00e1 sv\u011btla zcela nevymizela. Pro romantick\u00fd n\u00e1dech se udr\u017euj\u00ed nap\u0159\u00edklad v ulic\u00edch Lond\u00fdna. Na\u0161li bychom je i v n\u011bkter\u00fdch historick\u00fdch \u010d\u00e1stech na\u0161eho hlavn\u00edho m\u011bsta. U\u017e je ale neobch\u00e1zej\u00ed lamp\u00e1\u0159i, n\u00fdbr\u017e se rozsv\u011bc\u00ed automaticky.
