Western Slope Skies - Headlights

Have you traveled along a dark road and been temporarily blinded by bright oncoming headlights? I think we all can relate.Vehicle headlights are among the most widespread and least regulated sources of artificial light at night. A full moon produces roughly 0.1–0.3 lux. Lux measures how bright light appears on a surface, specifically the amount of light that falls on a given surface. One lux equals one lumen per square meter. Lumens measure the total light output from a source. Lux depends on distance and beam focus: the closer you are to a light source or the more focused the light beam, the higher the lux reading.
