Such barricades shall be protected by suitable and sufficient electric battery operated flashing lights. Such lights shall be kept burning from twilight in the evening through the night. Flares, lanterns, "bombs" or other devices using a flame shall not be permitted.
Defects in pavement shall be barricaded to prevent injury, and any person properly maintaining an opening or excavation in such place shall guard such opening or excavation while the same remains open, by proper barricades and lights described in the preceding paragraph of this section. (1972 Code)
