Car headlights are bright and dangerous, but why? Maybe you've noticed: In the past 10 years, car headlights have become extremely bright. So bright that it is often very difficult to see the road when driving by an oncoming vehicle. But, headlights haven' always been like this. This is a story between car manufacturers and consumers.

    Not because lumens. Putting led bulb behind the optics of headlights, whether if it’s projector or reflector is called lux. Driving cars with halogen headlights are not bright enough, not safe enough, and u can’t jack shit on the road. With the correct type of led bulbs. Me and my family feel much better and much safer to see better at night with right type of led bulbs like Lasfit, Auxito, and Sylvania led without blind others. As long as it mimics the same beam pattern, fix the correct beam pattern height, fix the orientation of the led bulb facing 3-9 o’clock position, make sure the led two sided chips are the same size as the coil filament. U will be fine.

    When you talk about the ghost forest and the land plummeting 2 meters, it also moves west at the same time. So not just up and down but side to side as well. This is important to think of it moving in three dimensions as the crust rebounds because not all of the crust drops but also lifts at the front edge of the subduction. Teaching just the drop part is not giving the students the big picture of what's happening to the crust when the earthquake is happening.

    "Volga river is the largest river in Russia" - that's literally shocked me: how in the 21st century it's even possible for someone with access to the internet to say such nonsense? Dude, the Volga is only the 5th/6th largest river in Russia! The largest would be the Lena. I mean, you're making a video, not just having a small talk with your friends! Where did you get this information? You just pulled it out of your head? That's not how you make videos, that's a China-level quality. Where did you get your education? College probably did a bad job. I'm sorry, but it is what it is - you need to read something before making a video, you're not talking about science fiction. And your video just consists of such mistakes. For example, you've mentioned Russia's ports that freeze during the winter, but what about ports that don't freeze during the winter months? Of course, it would be great for Russia to have more warm water ports, but Russia already has several of them and you didn't mention them in the video: Murmansk on the Arctic Ocean, Kaliningrad and Baltiysk on the Baltic Sea, Novorossiysk, Tuapse, Sevastopol, Yalta, Feodosiya on the Black Sea, Kerch and Port-Kavkaz between the Black and Azov seas, Nevel'sk, Holmsk and Zarubino on the Sea of Japan, and also - Petropavlovsk-Kamchatskiy located in the second largest natural harbor in the world - Avacha Bay on the Pacific Ocean. All of them don't freeze throughout the year. And since Russia has the biggest in the world fleet of nuclear-powered icebreakers - is freezing of some ports such a big problem? Again, even ports that do freeze in winter months - they don't go on holidays at that time, they still work but with the help of ice-breakers they`re not "useless" for the winter time as you said in the video. Pure joke. Going next: you've talked about problems with agriculture - and again, problems with agriculture today are mostly due to Putin and his corrupt government which doesn't care about people and the country itself. It's not about geography: Russia has one of the most arable land in the world and which is even more important - most of the arable land in Russia consists of the most fertile type of soil in the world called chernozem - it`s even a Russian word (chernozem = black land/ground/earth), because this type of soil was found in Russia and Ukraine and now Russia still has around 55% of all world`s chernozem soils. I can even rely on my personal experience: i live in the central Ural mountains region and almost all of the food in local supermarkets is Russian-produced (it was like that even before sanctions and isolation) with a very good-quality (even with such a bad situation in Russian economy today). My region, for example is famous for its milk products. Of course before sanctions there were many products from all around the world (as you understand they have been replaced by russian analogs now and you need to go to a bigger supermarkets, shopping malls to find these products, but i personally don`t care, i still buy what i`ve always bought before), but still - fruits, vegetables, drinks, milk and bread products, candies, and all the other stuff possible - most of them are Russian produced. In winter such "tropical" stuff as watermelons and melons and others are come from the tropical countries but in summer - we have around 4 sorts of watermelons and melons in a small markets which come from the different Russians regions which produce them (and that`s considering that i live in a small town in the region that doesn`t produce watermelons or melons at all). And even without all of that i have said - your phrase "32% of Russia is too cold for agriculture" still makes no sense: it`s just sounds not logical. I can say "Most of the West of US is too hot for agriculture" - so what? It`s just sounds weird and wrong, 32% of Russia is not all of it and considering the fact how big Russia is - all of other 68% of its land is millions of kilometers. Also a point "Naval power equals power" - is pretty senseless in this world today, it might have been a thing a long times ago, but today - it doesn`t even matter in what country your factories are set up. Somehow Russia was one of the greatest military powers in the human`s history and with a pretty decent fleet, maybe with not that many free access options to the world`s ocean. And if we get back to water resources - seriously, Russia is on the 2th position in the world by total renewable water resources, only Brazil has more of them. Lake Baikal itself has around 20% of the world freshwater resources. The 1th and 2th biggest lake in Europe (without Caspian Sea) - Ladoga and Onega which are located in Russia are not consist of the fake water too, you know. And talking about rivers in Russia - there are 2 rivers in Russia that are bigger than Mississippi: Lena and Yenisei. There`s lots of navigable big rivers both in European and Asian Russia. "The East of Russia is protected only by the cold of Siberia" - is just "lmao" to say the less. You probably never heard of Russia has 8 climate zones and Siberia itself has 4 climate zones (that`s without Far East of Russia which has 4 other climate zones). Also seems like you forgot about seas and oceans - isn`t they one of the best protections against invasion?) And even if we`re talking about land borders - Far East of Russia and Siberia are covered with many different endless mountains and volcanos - does that say something to you? These mountain ranges are even sit on almost all of Russia Pacific coast making invasion even without a cold winter (if it was cold in Far Eastern Russia) impossible. Only West Siberia has almost no mountains (only Ural mountains which separate Europe and Asia) - but, surprise - West Siberia is a one big swamp. We can add to this list of natural protectors one of the biggest forests in the world - Siberian taiga. Siberia and Far East wouldn`t have to worry about the invasion even if they were tropics. And finally, your statement that "Russia is poor because of its geography" makes me laugh. Lots of natural resources such as water, forests, oil, gas, coal, gold, diamonds, etc. - i guess because of that Russia is poor. If you`re trying to say that it is hard to manage - well, i`m sure you didn`t study history of the United States well. It`s about overcoming negative aspects of your country`s geography and maxing out benefits of your country`s geography. US did it and now you can find tons of videos of how "US blessed with its geography and that`s why they are rich" - but nobody now remembers the unsuitable for agriculture Great plains, dry, boiling hot and covered with mountains Wild West and suffering from Hurricanes and diseases Southwest. US could sit and do nothing today saying "what`s the reason to develop southwest if every year Hurricanes and Floods destroying infrastructure there?" or "why we need to build economy in Texas and Arizona - it`s too hot and dry there, all of local resources wouldn`t make us going there and building something there!" - but US just overcome some disadvantages of their land and used their advantages so nowadays people think that in US land there`s not even a single problem with America`s geography. Geography plays it`s role, but to say the country x is poor just because of its geography - is going against what history science and economy teach us. Again, sorry, but those non-scientific conclusions - i just can`t stand them and it doesn`t matter what language do you speak and in what country do you live: if you don`t know something - just don`t pretend that you do! This is the problem of most people on this planet, but which is worse - when people who don`t know something but despite it decide to talk about it.

    Most of the problem comes from car owners themselves trying to make their car seem "better" by replacing the halogen bulbs with LEDs, which do not work properly with the optics in halogen fixtures. Halogen bulbs have a single filament which is a single bright point, while retrofit LED bulbs typically have an array of LEDs spread out over a large area. The lenses and reflectors in halogen fixtures are not designed for an array of LEDs so they send light in random directions. Some car owners love retrofit LEDs because many cars only offer LED lighting on the "premium" model, so swapping the halogens for LEDs they believe makes people assume their have a premium model. Also, people with older cars that never offered LEDs tend to install them to make their car appear newer than it is.

Now 2024 the path crosses like a great big X from SW to NE marking Carbondale as 90 miles north of the New Madrid late-for-quake which was last predicted for an opposite pull of solar and lunar tug (which is how i discovered the matching mythology to 1918bc July 18 sothic star rising with a 7am quake in the year Shem Melkizedek age 550 went to Abram and predicted it in year 452) giving us the magic-X marks the spot from two eclipses 2017/2024 for earthquakes at 7am and 7pm.

    You sound young. I'm 65. Been driving since a teenager. When I started to drive cars had round headlights with (dual) tungsten filament incandescent bulbs. They were not particularly bright but the lenses were scientifically designed for both efficiency and control. Full beam is up and straight ahead, dipped is down to the side of the road. Halogen bulbs started appearing in the 1970s, not 1959. They were much brighter. That was a plus for high speeds but unfortunately the timing also coincided with the widespread adoption of wedge shaped headlight lenses. At that point I believe designers totally lost control of vehicle lighting. I am very aware of lightbulbs, being a collector of antique scientifically designed (Holophane brand) light reflectors and refractors, and only tungsten bulbs provide a controllable single point light source. All other bulb types fail. They copy the shape of tungsten bulbs but do not do the same job. (A bit like things made in China that look like familiar objects but fail to function like them.) I was taught lighting design at architecture school. In the domestic and office environment we were taught that fluros are okay for background lighting but not for work lights. Fluros always flicker at 50Hz, and not being a single point source create light without shadows. It is maddening, literally. A life without shadows drives you nuts. (We were also taught not to paint a child's room with walls and ceiling same colour: creates the same effect as whiteout in the snow.) While at university I spent one summer working with the university electricians changing bulbs and tubes, a lecture theatre at a time. I became very familiar with them. Taking a break from architecture school I worked for a few years as a gibstopper (drywall plasterer) just as halogens were being introduced for domestic use. What a lot of nonsense that was. The same time as downlights became popular. A million nasty bulbs throwing light at the floor and leaving the ceiling dark: how nuts is that! The global warming nonsense has put paid to tungsten bulbs and so I have been forced to try out other light sources. In a fully enclosed reflector-refractor compact fluros are adequate and less likely to burn out wiring. LEDs are absolutely hopeless. It is very hard to get a reflector to control them. I have read about the widespread installation of 5G cellular networks and how these have been sold by having streetlighting included in the package, LED of course. What I read is that the LED lighting is driving the wildlife crazy. I assume the same goes for humans too. No other artificial light source is better match to the human eye and brain combination the the single point light source tungsten filament incandescent bulb. So, your timing was a bit out on the halogens so you probably were not around to see the start of the failure of car lighting. Later types of lighting just got worse. On top of the lighting technology other technologies contribute to bright light effects. The change in car shape to avoid pedestrian harm, followed by the popularity of SUVs raised the height of headlights, making it harder to control intrusion of light into the cabins of other cars. And improved breaking means that drivers are inclined to follow closer again leading to light intrusion. I do not see any improvement in the near future.
