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). If the check engine light comes on, here are some tips on what you should do: If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.  Similar disorientation has also been noted for bird species migrating close to offshore production and drilling facilities. Studies carried out by Nederlandse Aardolie Maatschappij b.v. (NAM) and Shell have led to development and trial of new lighting technologies in the North Sea. In early 2007, the lights were installed on the Shell production platform L15. The experiment proved a great success since the number of birds circling the platform declined by 50 to 90%.[66] Dash lights are nothing new, but the messages are. The following list of warning lights are the most common lights used by auto manufacturers. Not all warning lights are universal. Always refer to your owner’s manual when you’re not 100% sure what the light indicates. 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. Central to Dorst’s frame creation model (2015 Dorst, K. (2015). Frame innovation: Create new thinking by design. Cambridge: The MIT Press. [Google Scholar]) is the great length that designers go to assess the frameworks through which problems are approached. Complex problems—such as the impacts of artificial nighttime lighting—are often caused by underlying value conflicts, and the inability of current frameworks to adequately address said values. By looking into the origins and history of the problem, the key driving issue, and the current context, a more comprehensive picture of the problem and underlying values emerge. And simultaneously the possibility of new approaches, or frames, will also emerge (Dorst, 2015 Dorst, K. (2015). Frame innovation: Create new thinking by design. Cambridge: The MIT Press. [Google Scholar]). However, for our present purposes we will not search for a new or radically different approach, but rather ask how the coalescing frame of light pollution is responding to our problem. We have our core issue present in the novel challenge described above. The next steps are to examine the origins and current context in turn, so see how light pollution can be improved as an effective frame. To precisely measure how bright the sky gets, night time satellite imagery of the earth is used as raw input for the number and intensity of light sources. These are put into a physical model[26] of scattering due to air molecules and aerosoles to calculate cumulative sky brightness. Maps that show the enhanced sky brightness have been prepared for the entire world.[27] For more information on how to get involved, you can contact the IDA directly. (And to learn more about light pollution, you can also watch “Losing the Dark,” a short planetarium show and video on light pollution produced by the IDA.) New LED streetlights have a small box on top of each column that flash a very small red and blue light. Please do not report any streetlights found to have these on, as this is to confirm that they are connected to our central management system. Some studies suggest a link between exposure to light at night, such as working the night shift, to some types of cancer, diabetes, heart disease, and obesity. That’s not proof that nighttime light exposure causes these conditions; nor is it clear why it could be bad for us. But we do know that exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms, and there’s some experimental evidence (it’s very preliminary) that lower melatonin levels might explain the association with cancer. 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. You can report a non-urgent fault with a street light by using the ‘Report now’ button below or phoning the Fault Line on 0845 601 0939, Monday to Friday from 8am to 5pm.  To place an attachment on a street light owned by us, you need to get a licence. 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. For a long time, solution two was very popular, and while it is less popular today, it continues to have a wide following (the late Henry M. Morris, Jr. was fond of this solution). Proponents argue that by its very nature, creation must include some “appearance of age,” for plants, animals, and people were not made as embryos or infants, but as mature adults, even though they did not go through the normal process of growth to reach adulthood. We certainly see this is true of Adam and Eve, but it also would seem to be true of plants, or else they could not fulfill their God ordained purpose of providing food only 2–3 days after they appeared if they were not mature (Genesis 1:29–30). Similar reasoning applies to many animals. Thus, the stars could not fulfill their purposes unless they were visible right away, so God made them with their light already en route to earth. This has a certain amount of appeal to it, but it also could be construed as deceptive on the part of God to make light containing tremendous amount of information of physical processes that never happened. Since the vast majority of the universe is more than a few thousand light years distant, it would seem that we will never see light that actually left these distant objects, and hence much of the universe amounts to an illusion. This concern has been the primary motivation of those seeking other solutions to the light travel time problem. under natural sunlight, starlight, and moonlight, with their associated natural cycles and seasons. All living things have natural biorhythms that work together with these natural sources of light. There weren’t always the artificial sources of light that we now have in the modern world, such as our street lights, lights from vehicles, electronics, billboards, and buildings, and many other sources of artificial human-created lights. While this abundance of artificial light has given us many advantages in our modern world, it is having many negative consequences on ourselves, our environment, and on all other living things.
