Not convinced that extra lighting is a problem? Check out these nighttime satellite views of Earth, courtesy of NASA’s Suomi NPP satellite. Additional images from Suomi NPP taken between 2010 and 2016 clearly show how light pollution is on the rise around the globe. 7. By wasted, we can assume this percentage of lighting is deemed to fall within one (or more) of the categories listed above (skyglow, glare, light trespass, or clutter). The big bang model assumes that the universe is many billions of years old. While this timescale is sufficient for light to travel from distant galaxies to earth, it does not provide enough time for light to travel from one side of the visible universe to the other. At the time the light was emitted, supposedly 300,000 years after the big bang, space already had a uniform temperature over a range at least ten times larger than the distance that light could have travelled (called the ‘horizon’)11 So, how can these regions look the same, i.e. have the same temperature? How can one side of the visible universe ‘know’ about the other side if there has not been enough time for the information to be exchanged? This is called the ‘horizon problem’.12 Secular astronomers have proposed many possible solutions to it, but no satisfactory one has emerged to date (see Attempts to overcome the big bang’s ‘light-travel–time problem’). One example of a lighting plan assessment can be seen in a report originally commissioned by the Office of the Deputy Prime Minister in the United Kingdom, and now available through the Department for Communities and Local Government.[97] The report details a plan to be implemented throughout the UK, for designing lighting schemes in the countryside, with a particular focus on preserving the environment. We’re converting many of our street lights to energy-efficient Light Emitting Diode (LED) technology. Read more about our LED street lighting project.

However, using the definition of “light pollution” from some Italian regional bills (i.e., “every irradiance of artificial light outside competence areas and particularly upward the sky”) only full cutoff design prevents light pollution. The Italian Lombardy region, where only full cutoff design is allowed (Lombardy act no. 17/2000, promoted by Cielobuio-coordination for the protection of the night sky), in 2007 had the lowest per capita energy consumption for public lighting in Italy. The same legislation also imposes a minimum distance between street lamps of about four times their height, so full cut off street lamps are the best solution to reduce both light pollution and electrical power usage. In September 2009, the 9th European Dark-Sky Symposium in Armagh, Northern Ireland had a session on the environmental effects of light at night (LAN). It dealt with bats, turtles, the “hidden” harms of LAN, and many other topics.[76] The environmental effects of LAN were mentioned as early as 1897, in a Los Angeles Times article. The following is an excerpt from that article, called “Electricity and English songbirds”: The radical effect of the electric lightbulb cannot be overstated. More than any lighting technology that preceded it—candles, oil lamps, or gas lighting—the electric light revolutionized the night. Now the darkness, at least in cities, was in full retreat. eService – Report damaged streetlights  Section 2 discusses the moral and political significance of framing problems, in relation to the novel environmental problem of excess artificial nighttime lighting in cities. Section 3 then analyzes the concept of light pollution in detail. Here, both the origins of the concept and its current manifestations are presented, in order to provide a more comprehensive understanding of light pollution. Section 4 returns to the question of how light pollution frames concerns and possible responses, and discusses two interrelated questions: the potential limitations of the concept as a normative or prescriptive tool, and the ambiguities and inconsistencies in its practical application that require clarification. Thus, first steps are taken in dissecting the ethical significance of the concept of light pollution and the role it can play in addressing the adverse effects of artificial nighttime lighting.

According study conducted by CarMD, five common malfunctions cause the check engine light to come on, and several of them are simple to fix yourself. Let’s take a look at the most common issues. Currently, the most popular idea is called ‘inflation’—a conjecture invented by Alan Guth in 1981. In this scenario, the expansion rate of the universe (i.e. space itself) was vastly accelerated in an ‘inflation phase’ early in the big bang. The different regions of the universe were in very close contact before this inflation took place. Thus, they were able to come to the same temperature by exchanging radiation before they were rapidly (faster than the speed of light1) pushed apart. According to inflation, even though distant regions of the universe are not in contact today, they were in contact before the inflation phase when the universe was small. Gaslight was followed by the invention of electric lighting in the latter half of the nineteenth century—the most profound technological development in lighting, and arguably one of the most important developments of modern infrastructure. Figuratively, electric lighting became synonymous with—and symbolic of—modern progress. For a Russian poet visiting New York City in the 1920s, the bright electric lights were perceived as modernity’s very medium (Isenstadt, 2014 Isenstadt, S. (2014). Good night. Places Journal. Retrieved 22 October, 2014, from https://placesjournal.org/article/good-night/[Crossref] [Google Scholar]). Aided by various technical advances, for example, floodlights, electric lighting quickly became a ‘sophisticated cultural apparatus’ that could be used for advertising, commemorating history, expressing civic pride, highlighting monuments, etc. (Nye, 1990 Nye, D. E. (1990). Electrifying America: Social meanings of a new technology, 1880–1940. Cambridge: MIT Press. [Google Scholar], p. 73). Via electrification, artificial nighttime lighting became, and remains, a prolific technological artifact capable of esthetic and ideological expression well beyond functional requirements.44. 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.View all notes According study conducted by CarMD, five common malfunctions cause the check engine light to come on, and several of them are simple to fix yourself. Let’s take a look at the most common issues. This did not fix the problem. The two bulbs were still coming on dimly at the same time when pressing the brake pedal.  Now I should turn this into a contest. You electrical wizards out there may already have a good guess.  In all my years of working on all types of cars – almost every time I have run across a problem with front and rear lights doing weird things – and by that I mean not glowing brightly, cross feeding, coming on at the wrong time, intermittent operations, etc, etc, it has almost always turned out to be an electrical grounding problem.  And it was no different here.  I took a close look at the grounding strap connecting points and I could see corrosion.  I applied some dielectric grease and squeezed the contact points together with some needle nose pliers and Wallaah – the running bulb went off and the brake light bulb came on super bright.  A good day and another one fixed.
