Zorin OS's auto-brightness feature has this bug that I like to call "Brightness Runaway," where, if it's semi-dark in the room you're in, loading a webpage with a Light Mode UI will throw enough light onto you (and the things around you) that Zorin OS will think it suddenly got brighter in the room.

That causes the auto-brightness to raise itself, which causes more light to be thrown into the room. That causes the auto-brightness to think it got even brighter, which causes it to raise the brightness even more.

The brighter it gets, the more auto-brightness tries to raise the brightness, and the more auto-brightness tries to the raise the brightness, the brighter it gets, so eventually you end up sitting there like:

Sat, youre sometimes more concerning than brightness

I am on tumblr - I see a post. Do I have to increase my screen brightness? Then it's a Hannibal post.

We like to admit to only that which already glows, although it is nobler to support brightness before it glows, not afterwards.

Why Have Vehicle Headlights Gotten So Bright in Recent Years?

The increasing brightness of vehicle headlights is driven by advancements in lighting technology, evolving safety standards, and shifts in automotive design trends. Here’s a detailed breakdown of the key factors:

​​1. Technological Advancements in Lighting​​ • Shift to LED and Laser Systems:

Modern vehicles increasingly use LED (Light Emitting Diode) and laser headlights, which produce significantly brighter and whiter light compared to traditional halogen or HID (High-Intensity Discharge) bulbs. LEDs are up to three times brighter than halogens while consuming less energy . Laser technology, though less common, offers even greater intensity and precision, illuminating farther distances with minimal power usage . • Example: LED headlights emit "blue light," which the human eye perceives as harsher than the "yellow light" of halogens, contributing to the perception of increased brightness .

• Adaptive and Smart Features:

Innovations like Adaptive Driving Beams (ADB) and matrix LED systems adjust beam patterns dynamically based on road conditions, vehicle speed, and surrounding traffic. These systems maximize illumination without blinding other drivers, allowing automakers to safely increase brightness .

​​2. Safety Regulations and Ratings​​ • Stringent Safety Standards:

Organizations like the Insurance Institute for Highway Safety (IIHS) now rate vehicles based on headlight performance, pushing manufacturers to improve illumination. For example, a "good" IIHS rating requires headlights to illuminate at least 325 feet ahead—a standard that incentivizes brighter systems . • Compliance with these standards often requires advanced technologies like HID or LED lights, which outperform older halogen systems .

• Global Regulatory Pressure:

Regulations in regions like the EU and U.S. mandate better nighttime visibility to reduce accidents. This has accelerated the adoption of high-performance lighting systems .

​​3. Vehicle Design Trends​​ • Rise of SUVs and Taller Vehicles:

The growing popularity of SUVs and trucks—which sit higher off the ground—means headlights are mounted at elevated positions. This increases the likelihood of glare for drivers of lower vehicles, even if the brightness itself hasn’t changed . • SUVs now account for nearly 46% of global vehicle sales, amplifying this issue .

• Aesthetic and Functional Integration:

LEDs and lasers allow sleeker, more customizable designs (e.g., slim light strips or intricate patterns), which automakers use to enhance brand identity. Brighter lights are often marketed as a premium safety feature .

​​4. Human Factors and Perception​​ • Aging Drivers and Eye Sensitivity:

Older drivers, who represent a growing demographic, are more susceptible to glare due to age-related eye conditions like cataracts. While brighter lights improve visibility for the driver, they can disproportionately affect oncoming traffic .

• Misalignment and Poor Maintenance:

Even advanced headlights can cause glare if improperly aligned. Studies show that many vehicles fail roadworthiness tests due to incorrectly aimed beams, exacerbating brightness issues .

​​5. Environmental and Efficiency Demands​​ • Energy Efficiency:

LEDs and lasers consume less power than halogens, reducing strain on vehicle electrical systems and improving fuel efficiency—a critical factor as automakers prioritize sustainability .

​​Key Takeaways​​ • Brightness vs. Safety Trade-off: While brighter headlights enhance driver visibility, they risk blinding others. Solutions like adaptive beams and stricter alignment regulations aim to balance these concerns .

• Future Trends: Emerging technologies like Digital Light Systems (e.g., Mercedes' DIGITAL LIGHT) project dynamic patterns onto roads, further optimizing illumination without excess glare .

For drivers struggling with glare, tips include using anti-reflective coatings on mirrors, cleaning windshields regularly, and opting for night-driving glasses .

First time asking anything so sorry if it's stupid

But I wanted to know if you guys celebrate Christmas? Maybe with a party?

Prime: "yeah, we do actually"
