🚦 Who Really Invented the Modern Traffic Light?
The modern traffic light, largely attributed to Garrett Morgan’s 1923 invention, introduced a critical yellow warning light that improved public safety. Despite his significant impact on traffic systems, Morgan’s contributions have often been overlooked due to historical racism.
Last Updated on February 14, 2026 by Daily News Staff
When you think about the traffic light, you probably picture green for go, red for stop, and maybe a frustrated glance at the yellow. But have you ever stopped to ask: Who actually invented this system we take for granted every day?
The story of the modern traffic light isn’t just about technology—it’s about innovation, public safety, and a Black inventor named Garrett Morgan who changed the way we move through the world.
🔦 Early Traffic Signals: A Dangerous Beginning
Before cars dominated streets, early attempts at traffic control involved manual policing and hand signals. In 1868, the first gas-powered traffic signal was installed in London outside the British Houses of Parliament. Designed by J.P. Knight, a railway engineer, this early signal exploded after just a month due to a gas leak—killing a police officer and abandoning the idea for years.
As cars became more common in the early 20th century, so did traffic jams—and accidents. Cities needed a safer, more efficient solution.
🛠️ Enter Garrett Morgan
In 1923, Garrett Morgan, an African-American inventor and entrepreneur from Cleveland, Ohio, received U.S. Patent No. 1,475,024 for a traffic control device that added a crucial feature: a “warning position” between stop and go. This idea is the basis for today’s yellow light.
His signal was:
- Manually operated
- T-shaped
- Designed to be mounted on a post
- And included a buffer phase to clear intersections before switching direction
This innovation was not only about traffic flow—it was about safety and preventing collisions at a time when automobile fatalities were rapidly increasing.
Morgan sold the rights to his invention to General Electric for $40,000 (equivalent to over $700,000 today), though his contributions were overlooked for decades.

⚙️ Was Morgan the
Only
Inventor?
No. Traffic signal history has multiple contributors:
- Lester Wire, a Salt Lake City policeman, created an electric traffic light prototype in 1912.
- William Ghiglieri patented an automatic signal in 1917.
- Garrett Morgan’s version stood out for its practical innovation—the transitional phase—and for being one of the first widely adopted and commercially viable versions.
In other words, Morgan helped move the traffic light from an experimental device to a nationwide safety standard.

✊ Why Garrett Morgan Deserves More Recognition
Garrett Morgan’s impact goes far beyond traffic lights. He also invented a gas mask used by firefighters and soldiers, and he launched one of the first Black-owned newspapers in the U.S.
He was a true innovator, working in an era where his contributions were often ignored due to racism. Today, we honor his legacy by telling his story and recognizing how his vision saved countless lives.

🌕 Blood Moon Over Arizona: Total Lunar Eclipse Visible in Phoenix on March 3, 2026
Last Updated on March 2, 2026 by Daily News Staff
Early risers in Arizona are in for a celestial show.
On Tuesday, March 3, 2026, a total lunar eclipse will be visible across much of North America — including Phoenixand the Valley. During this event, the Moon will pass completely into Earth’s shadow, turning a deep copper-red color often called a “Blood Moon.”
Here’s what you need to know.

🌍 What Is a Total Lunar Eclipse?
A total lunar eclipse happens when the Sun, Earth, and Moon align perfectly, with Earth positioned directly between the Sun and the Moon. As the Moon moves into Earth’s darkest shadow (the umbra), it doesn’t disappear — instead, it glows red.
That reddish color comes from sunlight filtering through Earth’s atmosphere — essentially, we’re seeing all the world’s sunrises and sunsets projected onto the Moon at once.
🕒 Phoenix Viewing Times (MST)
Arizona does not observe Daylight Saving Time in March, so these times are in Mountain Standard Time (MST).
- 1:44 a.m. – Penumbral eclipse begins (subtle dimming begins)
- 2:50 a.m. – Partial eclipse begins (Earth’s shadow becomes clearly visible)
- 4:04 a.m. – Totality begins 🌕
- 4:34 a.m. – Greatest eclipse
- 5:03 a.m. – Totality ends
- 6:18 a.m. – Partial eclipse ends
- 7:20 a.m. – Penumbral eclipse ends

The most dramatic portion — totality — lasts nearly one hour.
🌅 Where to Look in Phoenix
The eclipse happens in the pre-dawn hours, so the Moon will be low in the western sky as it sets.
For the best view:
- Find a location with a clear western horizon
- Avoid city light glare if possible
- Consider desert viewpoints, parks, or elevated areas around the Valley
Because the Moon will be setting as the Sun begins to rise, the backdrop of early morning twilight could make for stunning photography.
🔭 Do You Need Special Equipment?
No.
Unlike a solar eclipse, lunar eclipses are completely safe to view with the naked eye. However:
- Binoculars enhance color detail
- A small telescope reveals subtle shadow gradients
- A tripod and DSLR or smartphone with night mode can capture impressive images
🌎 Why This Eclipse Matters
This will be one of the most accessible celestial events of 2026 for Arizona residents. Total lunar eclipses don’t happen every year in the same location, and the timing — just before sunrise — adds dramatic visual contrast.
If skies are clear, Phoenix could have a spectacular view.
📌 Quick Viewing Reminder for Phoenix
Set your alarm for around 3:45 a.m.
Step outside by 4:00 a.m.
Look west
Watch the Moon turn red
No tickets. No crowds. Just the sky putting on a show.

- Dulce de Leche Brownie — brownie with chocolate sauce, vanilla ice cream, dulce de leche and whipped cream
Hard Rock Hotels: curated listening experiences honoring female artists
Hard Rock Hotels will also highlight women in music through live performances, curated playlists and themed listening experiences using the brand’s Sound of Your Stay® program. Hard Rock says guests can expect music-themed amenities such as limited-edition vinyl, memorabilia highlights and playlists centered on female artists—both iconic names and emerging talent.
Events worldwide + Rock Shop merch
Hard Rock says it will host women-led performances, networking events, brunches and other community-driven experiences across its global footprint throughout March.

Brightline West Nears Final Environmental Clearance Milestone
Brightline West’s final environmental assessment is 99% complete, clearing a major hurdle for the high-speed rail line connecting Southern California and Las Vegas.
Last Updated on March 1, 2026 by Daily News Staff
The long-awaited high-speed rail connection between Southern California and Las Vegas just hit a major milestone.
According to recent reports, the final environmental assessment for Brightline West is now 99% complete — signaling that one of the most critical regulatory hurdles for the project is nearly finished.
For a project that has been discussed for over a decade, this is significant progress.
What “99% Complete” Really Means
Before major infrastructure projects like high-speed rail can move into full construction, they must go through extensive federal environmental review under the National Environmental Policy Act (NEPA).
For Brightline West, this includes:
- Environmental impact evaluations
- Wildlife and habitat assessments
- Air quality studies
- Noise and vibration analysis
- Cultural and tribal consultations
- Traffic and community impact reviews
Reaching 99% completion means the overwhelming majority of those studies, revisions, and agency approvals are essentially done. In practical terms, the project is nearly clear of its final federal environmental review requirements.
That’s a huge step toward full-scale construction.
The Route: Southern California to Las Vegas
Brightline West will run approximately 218 miles largely within the median of Interstate 15, connecting:
- Las Vegas
- Apple Valley
- Hesperia
- Rancho Cucamonga (with connections to Metrolink toward Los Angeles)
Trains are designed to reach speeds up to 200 mph, cutting travel time between Southern California and Las Vegas to roughly 2 hours.
Instead of battling I-15 weekend traffic, travelers could board a train in Rancho Cucamonga and arrive on the Las Vegas Strip in about the time it currently takes just to get through the Cajon Pass on a busy Friday.
Construction Status
The project officially broke ground in 2024, and early work has included:
- Geotechnical testing
- Land surveying
- Utility relocation
- Pre-construction corridor preparation
While heavy civil construction has not yet fully ramped up across the entire route, completing environmental clearance removes one of the last major barriers before large-scale building accelerates.
Timeline Update
The original goal was to open before the 2028 Los Angeles Olympics. That timeline has shifted.
Current projections place passenger service around late 2029, depending on construction pace and financing milestones.
Why This Milestone Matters
High-speed rail projects in the United States often stall due to environmental review delays, funding gaps, or regulatory challenges.
Getting to 99% completion on final environmental assessment means:
- Federal review is nearly wrapped
- Legal vulnerability is reduced
- Major construction can proceed with more certainty
- Investor confidence improves
For Southern California and Nevada, it represents real forward momentum.
The Bigger Picture
Brightline West is privately developed, separate from California’s state high-speed rail system. If completed as planned, it would become one of the first true high-speed rail lines operating in the western United States.
The I-15 corridor between Los Angeles and Las Vegas is one of the most heavily traveled leisure routes in the country. A successful rail alternative could significantly reshape travel patterns between the two regions.
Final Take
The headline may sound small — “99% complete” — but in infrastructure terms, it’s a major breakthrough.
With environmental review nearly finished, Brightline West is closer than ever to turning renderings into reality.
Now the question shifts from if the train gets built… to how fast construction can move from here.
