Generally speaking, the lighting of wedding lanterns does not depend on the lighting of street lamps, because it is designed to show gorgeous lighting effects at night. However, if the wedding double lights are placed in a very dark place, or additional lighting effects are needed, you can consider lighting up nearby street lamps or other lighting equipment to provide enough light to better display the beauty of lanterns.
In a word, whether it is necessary to light the street lamp needs to be decided according to the specific situation. If there is enough lighting in the venue, or the brightness of the wedding lanterns is bright enough, the street lamps may not be lit. However, if the lighting of the venue is dark, it may be a good choice to light the street lamps in order to better show the effect of the wedding double lights.
