The primary reason street lights appear orange is the use of sodium vapor lamps. These lamps contain sodium gas, which, when electrified, emits light in the yellow-orange spectrum.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sodium vapor lamps come in two main types:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Low-Pressure Sodium (LPS) Lamps:<\/b><span style=\"font-weight: 400;\"> They emit an almost yellow-orange light.

The human eye is more sensitive to yellow and orange light, which makes sodium vapor lamps particularly effective in low-light environments. Orange light scatters less than blue or white light, decreasing glare and improving visibility in foggy or rainy conditions.<\/p>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>\n<div class=\"row\"  id=\"row-1454639322\">\n\n\t<div id=\"col-1923168263\" class=\"col small-12 large-12\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n<div class=\"container section-title-container\" ><h2 class=\"section-title section-title-normal\"><b><\/b><span class=\"section-title-main\" >The History of Orange Street Lights<\/span><b><\/b><\/h2><\/div>\n<div class=\"container section-title-container\" ><h3 class=\"section-title section-title-normal\"><b><\/b><span class=\"section-title-main\" >The Evolution of Street Lighting<\/span><b><\/b><\/h3><\/div>\n<p><span style=\"font-weight: 400;\">Street lighting has evolved from gas lamps to hot bulbs before finally transitioning to sodium vapor lamps later.
