Massachusetts bans uber-bright aftermarket LED headlights and drivers couldn't be more thrilled

The details of the law are a little technical, but it's a good first step toward much tighter regulation.

It's impossible to see the road, other cars, and pedestrians when you're staring into someone's LED headlights.

I used to love driving at night. I'd just hop in the car and pick a direction and go, blasting music with the windows down and clearing my head along the way. It was truly one of my great joys. A lot of things were different back then, though. I had fewer responsibilities, for starters, and had time to just aimlessly wander. Gas was way cheaper, too, making these adventures far more economical.

But one big thing that has contributed to me losing my passion for night driving is absolutely, without a doubt, the rising prevalence of LED headlights. If you've ever wondered why everyone's headlights seem to be insanely, dangerously bright these days, you're not alone. And you're not the only one who's pissed off about it. What good is it to illuminate the road in front of you so well that you, in fact, blind the other drivers traveling at high speeds in your direction? How is that making anyone safer?

Just look at how infuriatingly dangerous these can be in real-world conditions:

The state of Massachusetts has reignited the conversation around LED headlights with a surprising new piece of legislation.

Many new cars come equipped with LED headlights, up to 75% or more of new models, in fact. But even more LED lights are sold as aftermarket options or conversion kits, and these are poorly regulated. Many aftermarket lights are far too bright and/or suffer from misalignment that shoots the light beams directly at the eye level of oncoming traffic. They represent a large portion of the glare problems we experience out on the road.

Massachusetts is cracking down with a new law. It states that LED headlights that come equipped from the manufacturer are fine (for now), but there will now be far stricter regulations on simply swapping in an aftermarket LED bulb or conversion kit onto your vehicle. The legislation specifically cites coloration and positioning issues with LED headlights that haven't been tested as a "full unit," meaning including the housing and reflectors that are typically part of a headlight.

So you could still legally upgrade from halogen bulbs to LED, but you'd have to replace the entire headlight unit and not just the bulb.

Hefty fines will be implemented for drivers who are caught in violation of the new policies.

LED headlights offer a lot of benefits, in theory. So why do people hate them?

LED lights use less power, are brighter (duh), and last far longer than traditional halogen bulbs.

But there are a few problems with the technology that make them a huge hassle for other drivers. First, they're just too bright! They look even brighter in real-life because of the pure/cool white they emit, versus the yellow glow of halogen bulbs. Cool colors like white and blue are harsher on the eyes than more night-vision friendly warm colors such as red, yellow, and orange.

Second, especially in America, we love huge vehicles. More and more people are driving trucks and jeeps that sit high. Now those ultra-bright LEDs are shining directly into the poor sedan drivers' eyes.

Third, too many Americans choose to drive with their high beams on at night — all the time. They like the extra visibility they get by dousing the entire roadway in bright light and have little regard for how dangerous it is for others in their path (or they simply forget they have them on). While a lot of American cars have high beams that can switch off when another car is detected, other countries have better technology at play.

Did you know that many cars in Europe and Asia feature a technology called ADB (Adaptive Driving Beam) that allows LED lights to shape and direct their light pattern in very specific ways on the road, actively avoiding the eyes of other drivers? US cars, so far, are not allowed to enable this mode — though the regulations are in the works.

Even still, assuming good alignment and ADB technology, bright LED headlights are a dangerous problem. They're causing accidents all over the world, and especially in America.

The legislation in Massachusetts is a good step toward even greater action. Organizations like the Soft Lights Foundation continue to fight for even stricter regulation of LED lights — and not just in cars — or even outright banning them.

And the public outcry for lawmakers to do something about the problem continues to grow. People are sick of being blinded in dangerous, high-speed situations. Hopefully more states will follow suit, and we can continue to pressure auto manufacturers to turn down the damn brightness.

Google Maps, Apple Maps, or Waze— former Uber driver shares which app is best

Do you agree? Not everyone did.

Google Maps/Apple Maps

Those of us of a certain age remember asking for directions and keeping two-inch thick road atlases in our cars to find our way around. Then with the internet came the miracle of Mapquest, followed by the how-did-we-ever-live-without-this GPS systems you could attach to your dashboard.

Then smartphones kicked the road trip game up a notch with map apps that not only give up step-by-step directions but also real-time traffic conditions and the ability to find a gas station or restaurant with gluten-free options along your route.

Even those of us who grew up with paper maps struggle to recall how we ever got anywhere before Google Maps.Now we're so deep into the map app era that we're past the wow stage and into the nit-picky stage. It's no longer good enough to have a handheld computer tell us how to get someplace in real time. Now we have expectations, preferences, opinions and complaints. We also have data and anecdotes with which to compare different apps and discuss which ones do what best.

And hoo boy do people have thoughts on that front.

Former Uber employee Flo Crivello shared some info on X about the analysis they did with three of the most popular map apps—Google Maps, Apple Maps and Waze—using a dataset with millions of trips.

The big winner? Apple Maps.

Google came in second, and Waze was a distant third (worst "by far").

"The research also included which apps people *thought* was worse, and the order came in the exact opposite order," Crivello shared. "We understood why Apple Maps got a bad rap given how bad it was at launch — it rapidly got better, but the brand stuck. Waze was more of a mystery, and we ended up realizing that people thought its routes were best because it was exposing them to so much info on traffic, construction, police presence etc… Everyone thinks they want a minimalist UI, but in practice, when they see all this info, they subconsciously conclude 'wow, these guys really have their sh*t together' — even when the routes were actually the worst ones."

Crivello said the results "may be shocking," presumably because Apple Maps started with the worst reputation. In fact, Apple CEO Tim Cook famously apologized for Apple Maps in 2012 and recommended people use Google Maps instead.

However, in the years since, Apple Maps has redeemed itself while Google Maps has lost a bit of its initial luster.



Then Waze came along, which people in cities with variable traffic touted as more accurate for timing and real-time updates, becoming some people's favorite. But according to his data eight years ago, Apple was the winner.

Do those results still hold? Some people in the replies said Google Maps was the best, hands down, while other said they preferred Apple or Waze.

It might depend on where you live and what you look for in a map app (and whether you even have access to Apple Maps). Discussions about these apps abound, with some common threads throughout. Many people agree that the U.S. is where Apple Maps shines, but Google Maps works better abroad. Apple Maps offers more natural navigation directions, such as "Not at this stop sign, but at the next one, turn right," instead of Google Maps' assumption that everyone knows how far 300 feet is. Google maps has great searchability and is easier to check reviews of places compared to Apple Maps. So opinions might vary on "best" depending on what you're using it for.

Waze has loyal users and people who love to joke about where it reroutes you when there's traffic.



These are not the only three map apps available, either. People who travel internationally and use public transportation seem partial to the CityMapper app, which makes finding train and bus routes simple with a user-friendly interface, so again, a lot depends on why you're using the app in the first place.

As far as popularity goes, Google Maps boasts a whopping 1 billion monthly users. In a recent MarketWatch study, 70% of respondents said they use Google Maps, particularly to avoid speed traps. In that study, both Apple Maps and Waze tied for second place. However, there is data that shows younger generations are partial to iPhones, on which Apple Maps is a native app, so it might have a bit of an advantage there.

Man climbs a 1,999-foot tower to change a light bulb. It looks as wild as it sounds.

Just another day at the office.

Man climbs 1999-foot tower to change a light bulb.

You know those big giant antennas that look like they reach just below the wing of an airplane at cruising height? Well, someone has to climb them every so often to inspect them or change the flashing bulb. You'd think it would be easier to have a helicopter or something drop them off, but there's probably a really compelling reason someone has to physically climb the antenna. If nothing else, it's probably a good workout.

For Nick Wagner, climbing these huge antennas is just another Tuesday at the office. Wagner works for a company called National Tower Controls, LLC, and apparently, they do maintenance on these towers annually. I'm not sure if there's some sort of process to decide who gets to be the one to climb the beast or if everyone that works there is expected to climb in some rotation. But Wagner took everyone on his climb to change out the light bulb and inspect KDLT-TV's antenna in 2015, and while the view is beautiful, I imagine it could also give you heart palpitations.

"Must not be afraid of heights" is likely in the job description multiple times, bolded, italicized and highlighted. It's not like if you get a little wobbly you can just step down. You'd need an airborne rescue team or a parachute, which makes you wonder if that's part of their climbing equipment. In the video, the climb itself took nearly 15 minutes and it's not clear where in the climb Wagner started filming, but the view is so spectacular that you can practically see the curvature of the Earth.

According to HuffPost, the KDLT-TV antenna's 1,999 foot height makes it not only one one of the tallest structures in South Dakota where it stands, but one of the tallest structures in the world. It's beaten only by Burj Khalifa in Dubai, and the Tokyo Skytree.

TV and radio are, of course, important, but the sheer height and might of the KDLT-TV antenna are dizzying to think about even if you aren't the one climbing the tower. In short, why does the antenna have to be so high? The answer is really simple: "the higher the mast, the farther the signal can travel." Can't argue with that.

What makes this whole process even more interesting is that if someone were to ask what he did all day, Wagner's answer could be, "I changed a light bulb," and he wouldn't be lying. He would be severely understating his duties, but he wouldn't be lying.

At any rate, Wagner can have those light bulbs and I'll stick to the ones that require no more height than a kitchen chair.

A student accidentally created a rechargeable battery that she says could last 400 years

"This thing has been cycling 10,000 cycles and it’s still going." ⚡️⚡️

Steve Zylius/University of California, Irvine.

UCI doctoral candidate Mya Le Thai has developed a nanowire-based technology that allows lithium-ion batteries to be recharged hundreds of thousands of times.

There's an old saying that luck happens when preparation meets opportunity.

There's no better example of that than a 2016 discovery at the University of California, Irvine, by doctoral student Mya Le Thai. After playing around in the lab, she made a discovery that could lead to a rechargeable battery that could last up to 400 years. That means longer-lasting laptops and smartphones and fewer lithium ion batteries piling up in landfills.

A team of researchers at UCI had been experimenting with nanowires for potential use in batteries, but found that over time the thin, fragile wires would break down and crack after too many charging cycles. A charge cycle is when a battery goes from completely full to completely empty and back to full again.

But one day, on a whim, Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

"She started to cycle these gel capacitors, and that's when we got the surprise," said Reginald Penner, chair of the university's chemistry department. "She said, 'this thing has been cycling 10,000 cycles and it's still going.' She came back a few days later and said 'it's been cycling for 30,000 cycles.' That kept going on for a month."

This discovery is mind-blowing because the average laptop battery lasts 300 to 500 charge cycles. The nanobattery developed at UCI made it though 200,000 cycles in three months. That would extend the life of the average laptop battery by about 400 years. The rest of the device would have probably gone kaput decades before the battery, but the implications for a battery that that lasts hundreds of years are pretty startling.

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said Penner added. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most. ”"The big picture is that there may be a very simple way to stabilize nanowires of the type that we studied," Penner said. "If this turns out to be generally true, it would be a great advance for the community." Not bad for just fooling around in the laboratory.

Since her discovery, Mya Le Thai has gone on to a successful career as the Principal Scientist with the Enevate Corporation,
