Apparent problems with a ceiling light fixture are usually traced to some issue that is interrupting the flow of electricity from the wall switch to the light fixture. Diagnosing the problem will depend on whether the light bulb does not light up at all, or if it is flickering intermittently.  The relationship between safety and lighting at night is complex at best, and often controversial. Historical surveys into the origins of public nighttime lighting (e.g. Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar]) describe the storied relationship between the value of safety and lighting efforts. Lighting served the practical function of making nighttime travel safer, but also the symbolic function of protection from the evils of the night (spirits, demons, etc.). In contemporary discourse, the exact relationship between safety and security and nighttime lighting remains contentious, with various studies proving or disproving a correlation (Pottharst & Könecke, 2013 Pottharst, M., & Könecke, B. (2013). The night and its Loss. In Space-time design of the public city, urban and landscape perspectives (Vol. 15, pp. 37–48). Dordrecht: Springer.10.1007/978-94-007-6425-5[Crossref] [Google Scholar]). It is outside the scope of this paper to comment on these studies in detail, but it is important to note that advocates for mitigating light pollution often cite the possibility that less (or more wisely designed) lighting may improve safety and reduce crime (e.g. Bogard, 2013 Bogard, P. (2013). The end of night: Searching for natural darkness in an age of artificial light. New York, NY: Back Bay Books. [Google Scholar]; Henderson, 2010 Henderson, D. (2010). Valuing the stars: On the economics of light pollution. Environmental Philosophy, 7, 17–26.10.5840/envirophil2010712[Crossref] [Google Scholar]). Your Check Engine Light may be indicating a simple problem that’s easy to fix – such as a loose gas cap. Or, it could be a warning of a more serious problem that could damage your engine components. Finding out why your light is on now can save you money and trouble down the road. 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. eService – Report damaged streetlights  Approximately 50% of Council owned street lights operate on a part-night basis.  This means that about 14,000 street lights are switched off between 1am and 6am during British Summer Time and between midnight and 5am during winter.

Red light has the least power to shift circadian rhythm and suppress melatonin. Use this form to report a problem with a street light or a lit bollard. In certain cases an over-illumination lighting technique may be needed. For example, indirect lighting is often used to obtain a “softer” look, since hard direct lighting is generally found less desirable for certain surfaces, such as skin. The indirect lighting method is perceived as more cozy and suits bars, restaurants and living quarters. It is also possible to block the direct lighting effect by adding softening filters or other solutions, though intensity will be reduced. In the 1600s, Ole Roemer became one of the first scientists to make a measurement of the speed of light. Roemer observed the orbits of Jupiter’s nearest moon and recognized that its orbital period was observed to be approximately 22 minutes longer when measured from Earth when it was furthest from Jupiter compared to when it was closest to Jupiter. Roemer reasoned that the difference was due to the fact that it took longer for light from Jupiter to travel the extra distance when Earth’s position was on the opposite side of the Sun from Jupiter. The distance d2 is 2.98×1011 m greater than the distance d1. Determine Roemer’s estimate of the speed of light in the 1600s. In 1957, the U.S. Naval Research Laboratory conducted the first ever radar measurements of the distance from the Earth to the moon. By reflecting light from an Earth-based source off the moon and measuring the back-and-forth time of transit, scientists determined that the moon is approximately 3.84 x108 m from the Earth. Determine the time it takes light to travel from Earth to the moon and back. The below discussion is organized under two broad questions, with the aim of elucidating the moral limitations and practical ambiguities existing within the concept of light pollution, when considered as a framework for moral and political decision-making. These two sections should not be seen as mutually exclusive, but as actively informing one another. Use this form to report a problem with a street light or a lit bollard.

This concept provides a framework for categorizing the adverse effects of nighttime lighting, which advocacy groups and regulatory efforts are increasingly utilizing. However, the ethical significance of the concept has, thus far, received little critical reflection. In this paper, I analyze the moral implications of framing issues in nighttime lighting via the concept of light pollution. First, the moral and political importance of problem framing is discussed. Next, the origins and contemporary understandings of light pollution are presented. Finally, the normative limitations and practical ambiguities of light pollution are discussed, with the aim of strengthening the framework through which decisions about urban nighttime lighting strategies are increasingly approached. But we may be paying a price for basking in all that light. At night, light throws the body’s biological clock—the circadian rhythm—out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity. ¹ ² ³ ⁴ U.S. federal agencies may also enforce standards and process complaints within their areas of jurisdiction. For instance, in the case of light trespass by white strobe lighting from communication towers in excess of FAA minimum lighting requirements[13] the Federal Communications Commission maintains an Antenna Structure Registration database[14] information which citizens may use to identify offending structures and provides a mechanism for processing citizen inquiries and complaints.[15] The U.S. Green Building Council (USGBC) has also incorporated a credit for reducing the amount of light trespass and sky glow into their environmentally friendly building standard known as LEED. All of this can be traced to one thing: the curse of light pollution.  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.
