Light pollution is the adding-of/added light itself, in analogy to added sound, carbon dioxide, etc. Adverse consequences are multiple; some of them may not be known yet. Scientific definitions thus include the following: A full cutoff fixture, when correctly installed, reduces the chance for light to escape above the plane of the horizontal. Light released above the horizontal may sometimes be lighting an intended target, but often serves no purpose. When it enters into the atmosphere, light contributes to sky glow. Some governments and organizations are now considering, or have already implemented, full cutoff fixtures in street lamps and stadium lighting. Plenty of other possibilities for a check engine light are out there, but the above five are the most common. How long do you usually let the check engine light stay on before you do something about it? Street light or pole serial number The serial number can be found on a sticker or tag at eye level on the street light standard or pole. You can now report a street light problem with your smartphone, so it is easier to report it from the location. Visit on your smartphone and select “Report Street Light Problem.” The street lights on motorways and trunk roads are looked after by the Highways Agency, so any faults should be reported using their helpline (0300 123 5000). 4. Neumann’s’ Architecture of the Night (2002a Neumann, D. (Ed.). (2002a). Architecture of the night: The illuminated building. New York, NY: Prestel. [Google Scholar]) is arguably the most important recent study of nighttime illumination in architectural history and theory, linking the history of nighttime lighting with the history of modern architecture. Neumann mainly focuses on the esthetic and expressive qualities of ‘illuminated buildings’ throughout the nineteenth and twentieth centuries, providing the first comprehensive catalogue of relevant architectural projects. Lights on tall structures can disorient migrating birds. Estimates by the U.S. Fish and Wildlife Service of the number of birds killed after being attracted to tall towers range from 4 to 5 million per year to an order of magnitude higher.[65] The Fatal Light Awareness Program (FLAP) works with building owners in Toronto, Ontario, Canada and other cities to reduce mortality of birds by turning out lights during migration periods. Light pollution is the excessive or misdirected outdoor lighting that is threatening to destroy virtually all casual stargazing. Throughout much of the United States, for instance, millions upon millions of precious watts are wasted because poorly designed streetlamps send a portion of their light into the sky. But it’s not just stargazers who need to be concerned. While some may scoff at preserving the beauty of the night sky, there are other facets of light pollution that have a direct impact on all of us. Here are just a few examples: Unfortunately, research is showing that in the U.S.A. fully two-thirds of us live under skies so bright we have lost the view of the Milky Way. And this loss comes mostly from just plain bad lighting – lighting that is not even doing a good job of showing us things we need or want to see on the ground. The furthest objects visible, quasars, have been detected 13 billion light years away.[1] After allowing for the metric expansion of space,[2] this puts the lower limit of the age of the universe at near 13 billion years.[3] The methods of measuring distances to the billions of light years are rather complicated, but there are direct measurements well beyond the limits of YEC, using only parallax. There are the measurements of the supernova SN1987A at about 168,000 light years, and the Gaia space mission should obtain many distances of objects up to about 30,000 light years.[4] You’re driving along in your car or truck and suddenly a yellow light illuminates on your dash telling you to check or service your engine. If you’re like most car owners, you have little idea about what that light is trying to tell you or how you should react. Ten percent of all cars on the road have a Check Engine light on, and the drivers of half of these cars have ignored the light for more than three months, says Kristin Brocoff, a spokesperson for The company sells a $119 device that reads engine codes and provides access to a Web site database that identifies the problem (according to the code) and estimates the cost of repair. While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours). We will not fit a shade to new LED street lighting for the first 3 months after installation. If there is still an issue after 3 months, please report the problem. The German-born, American physicist Albert Michelson devoted much of his life to the accurate measurement of the speed of light. In 1923, he positioned mirrors and detectors on two different California mountains positioned nearly 35 km (nearly 22 miles) apart. Using a sophisticated timing method of involving the rotating of octagonal mirrors, Michelson determined the speed of light to be 299,774 km/sec. At this speed, estimate the time it takes light to travel 35 km between mountains. Recent creationists believe that the universe is only thousands of years old. The universe appears to be far larger than just a few thousand light years in size, suggesting the light travel time problem. However, by concentrating on the current age of the universe, we incorrectly formulate the light travel time problem. I recommend that we properly state the problem by noting that Adam had to see much of the universe at the conclusion of the Creation Week. The blinding effect is caused in large part by reduced contrast due to light scattering in the eye by excessive brightness, or to reflection of light from dark areas in the field of vision, with luminance similar to the background luminance. This kind of glare is a particular instance of disability glare, called veiling glare. (This is not the same as loss of accommodation of night vision which is caused by the direct effect of the light itself on the eye.) Check out the FAQ for commonly asked questions about The City street lighting program. The street lighting service looks after over 22, 000 street lights and illuminated traffic signs. Use the form below to let us know where the problem is.  Our field personnel typically address light issues within 72 hours of a reported issue. Urgent problems with street lights, illuminated signs or bollards are: Hartnett, J. 2003. A new cosmology: Solution to the starlight travel time problem. TJ 17, no. 2:98–102. Judging by the number of visible stars, my observations show that light pollution has made the night sky over Warrensburg, New York, about four times brighter since the mid-’70s. And at various points along the horizon, there are now small domes of light indicating the presence of nearby towns, the brightest of which is Lake George, a popular tourist center several miles to the south. The light fixtures in our homes are remarkably effective and may work for years with little attention other than replacing an occasional burned-out light bulb. Sometimes, though, a light fixture that’s been working fine may suddenly develop a problem that requires diagnosis and repair. The correction can be very simple—such as replacing the light bulb or adjusting the light bulb socket—or as complex as replacing the entire light fixture or a wall switch. Many warning lights indicate that a fault has occurred inside the vehicle’s system, but it doesn’t pinpoint the item or system that has failed. In these cases, a code reader or scan tool can help determine the part that needs to be replaced.
