A more responsive light photocell sensor\u00a0can turn lights on closer to the right moment at dusk and off closer to the right moment at dawn. That improves visual comfort and helps roads stay properly lit. Second, it affects stability.<\/p><p>\u00a0<\/p><p>A better photo sensor\u00a0can ignore short light disturbances and avoid needless switching. Third, it affects energy use.
