Should I turn my headlights on when driving during the day?

Using headlights during the day is not just a good idea—it can save lives. While daytime running lights (DRLs) or full headlights aren’t always legally required, their safety benefits are well-documented. Here’s a breakdown of when and why you should use them:

1. When to Turn On Headlights During the Day

Low Visibility Conditions: • Rain, fog, snow, or mist (even light drizzle). • Dawn/dusk ("twilight hours"). • Forested roads, tunnels, or shaded areas.

Legal Requirements: • Mandatory in some regions: ◦ Scandinavian countries, Canada, and parts of Europe require DRLs or headlights at all times. ◦ U.S. states like New York and New Jersey mandate headlights during rain. • Check local laws—many states require headlights if visibility drops below 500–1,000 feet.

2. Why Use Headlights During the Day?

Reduces Collisions: • Vehicles with lights on are 15–25% less likely to be involved in daytime accidents (NHTSA). • Critical for motorcycles, gray/silver cars, and low-contrast vehicles.

DRLs vs. Full Headlights: • DRLs: Automatically on but often lack taillights. Use full headlights in poor weather to activate rear illumination. • Full Headlights: Ensure all lights (front and rear) are visible.

3. Exceptions and Practical Tips

Clear, Sunny Days: • Optional but still beneficial (e.g., rural roads with glare).

Energy/Bulb Life Concerns: • Modern LEDs use minimal power (1–5 watts) and last 10,000+ hours. • Halogen bulbs cost ~$10–$20 to replace annually if used daily.

Auto Headlight Systems: • Enable "Auto" mode if your car has it—sensors activate lights as needed.

4. Penalties for Non-Compliance Scenario Potential Fine Driving without lights in rain (e.g., California) $100–$200 No DRLs where required (e.g., EU) €50–€150

Final Verdict Turn on your headlights during the day if:

You’re driving in any suboptimal visibility.

Your car lacks DRLs (use low beams).

Local laws require it.

The minor inconvenience of switching them on is far outweighed by the safety benefits. As the adage goes: "Be seen, not sorry." 🔆🚗

Earthspark Spoilers ahead

So, this is ES Orion Pax pre-matrix:

that dont look like an archivist, cop, or even a dockworker to me! Dockworker maybe, but surely they'd show him doing something more recognizable as that, like moving boxes or something?

He's definitely not a clerk or other whitecollar worker, which yay, i missed good ol blue collar laborer orion pax.

But i think its interesting, that he even looks a bit like he's mining.

This is important

Sometimes radical acts of self-love and asserting your adulthood mean that despite surviving a horrific year in your personal life, no one in your life bothered to buy you the Matrix Build-a-Bear you want need in your life and which will definitely go a ways toward healing your wounded spirit, so when it goes on clearance, you learn your lesson from all the times you tried to be """fiscally responsible""" and missed out on something you now can't have and you BUY YOURSELF THE DAMN BEAR because you DESERVE IT and because no one else cares and you're an ADULT so you take care of your GODDAMN BEAUTIFUL AND UNDEFEATABLE SELF YEAH dammit

Currently working for a huge company that is happy to see people fail, within the same overall Matrix this man describes. Appreciate this on several levels.

“The whole world’s a fucking casino. In a casino some of the smartest people in the world are doing everything to keep you gambling. They’ve taken the clocks off the wall. They’re pumping in oxygen. They’ve even thought about the patterns on the carpet. Everything has been scientifically engineered to keep you pulling that lever. And that’s our entire world now. It’s one big casino where some of the smartest people in the world are asking themselves: ‘What is the best way I can get people to eat more? What is the best way I can get people to watch more pornography? Or take more pills? How can I use artificial intelligence to serve people the exact succession of sixty second videos that will keep them staring at their screen for an entire day?’ I used to be a personal responsibility guy. A big reason for that is I have insane discipline. If I needed to completely stop eating candy for ten years, I could do it. Done. So if I ever saw someone who was obese, I’d think, I could do it. Put me in the exact same situation, and I’d lose the weight. But now whenever I see an obese person on the jogging trail, I just want to give them a hug. It’s almost enough to make me cry. I think God, this must be so fucking hard for you. And it’s going to take perfection: insane discipline, and time, and money, and listening to all the right podcasts. Every day of the week needs to be perfectly regimented. Five years of absolute perfection. That’s what it’s going to take. Because a ton of the smartest people in the world are getting paid massive amounts of money to figure out a way to make you fail.”

Interests suck so much! Like! Ough! Like, okay, going off TMA as an example but...

TMA is reminding me of Camp Here and There, so I want to go relisten to that, and also it's remining me of my lovely Lemon Demon phase, so I want to go like... listen to (in detail) a lot of Lemon Demon songs.

And the TMA Q&As are making me want to read a bunch of classic horror and read up on some of the non-fiction influencing TMA.

And also, me revisiting Lemon Demon is reminding me of my Will Wood phase (which is also tied up with CH&T), so now I want to listen to a bunch more Will Wood songs!

And also, obviously, now I want to get into The Mechanisms and listen to TMP.

But it's SO MUCH! There's so much art that I want to engage with, but it's too much to meaningfully engage with all of it.

How do I replace a headlight bulb?

Replacing a headlight bulb is a straightforward task you can often do yourself with basic tools. Here's a step-by-step guide to help you through the process safely and effectively:

---

**Tools You’ll Need**

• Replacement bulb (check your owner’s manual for the correct type, e.g., H11, 9005, or LED).

• Gloves (to avoid touching the bulb glass with bare hands, which can shorten its lifespan).

• Screwdriver (Phillips or flathead, depending on your vehicle).

• Socket wrench (optional, if bolts hold the headlight assembly).

• Clean microfiber cloth (to handle the bulb).

---

**Step-by-Step Instructions**

**1. Turn Off the Vehicle**

• Park on level ground, turn off the engine, and engage the parking brake.

• Let the headlights cool for 10–15 minutes if they were recently on.

---

**2. Access the Headlight Bulb**

• Open the hood and locate the headlight assembly.

• Remove the access panel:

• Some vehicles require removing a plastic cover or dust cap behind the headlight (twist or unclip it).

• Others may need partial removal of the bumper, battery, or air filter box (check your owner’s manual).

---

**3. Disconnect the Wiring Harness**

• Unplug the electrical connector from the back of the bulb by pressing the release tab and pulling gently.

---

**4. Remove the Old Bulb**

• Release the bulb:

• For halogen/HID bulbs: Twist the bulb socket counterclockwise (usually ¼ turn) to unlock it.

• For LED modules: Unclip any retaining rings or screws.

• Pull the bulb straight out from the housing.

---

**5. Install the New Bulb**

• Avoid touching the glass (halogen/HID bulbs) to prevent oil residue from shortening its lifespan. Use gloves or a cloth.

• Align the new bulb:

• Match the tabs or notches on the bulb base to the slots in the housing.

• For halogen/HID bulbs, insert and twist clockwise to lock.

• For LED bulbs, secure with clips or screws.

---

**6. Reconnect and Test**

• Plug the wiring harness back into the bulb.

• Turn on the headlights to test before reassembling.

• Check beam alignment: Ensure the light pattern is even and not pointing too high/low.

---

**7. Reassemble the Headlight**

• Replace the access panel or dust cap.

• Secure any parts you removed (bumper, battery, etc.).

---

**Common Mistakes to Avoid**

1. Touching the bulb glass (causes premature failure).

2. Forcing the bulb (align the tabs properly).

3. Using the wrong bulb type (check your owner’s manual).

4. Ignoring beam alignment (misaligned lights blind other drivers).

---

**Troubleshooting Tips**

• Bulb won’t work: Check fuses or the electrical connector for corrosion.

• Condensation in the housing: Let it dry or replace the seal.

• Sealed headlight assembly: Requires professional replacement.

---

**When to Seek Professional Help**

• If your vehicle’s headlight assembly is complex (e.g., requires bumper removal).

• If you’re replacing adaptive or matrix LED headlights (special tools/calibration needed).

---

**FAQ**

• Can I replace just one bulb?

Yes, but replacing both ensures consistent brightness.

• Are LED conversions legal?

Only if they’re DOT/SAE-compliant and properly installed.

---

By following these steps, you’ll save money on labor costs and ensure your headlights function safely. If unsure, consult your vehicle’s manual or a trusted mechanic! 🔧

Grove 8x8 LED Matrix am Arduino: Einsteigerfreundliche Programmieranleitung

In diesem Beitrag möchte ich dir zeigen, wie du die Grove 8x8 LED Matrix am Arduino UNO R3 programmierst. Der Vorteil von diesem Modul ist es, dass du keine umständliche Verkabelung vornehmen musst, da die Grove Schnittstelle einheitlich ist und ein vorkonfektioniertes Kabel verwendet wird.

Grove 8x8 LED Matrix am Arduino: Einsteigerfreundliche Programmieranleitung Im Beitrag Arduino Lektion 8: Max7219 8×8 LED Shield habe ich dir bereits ein ähnliches Modul mit dem Chip MAX7219 vorgestellt. Hier soll es nun um eine Matrix mit dem Treiber HT16K33 gehen.

Bezug einer 8x8 LED Matrix mit Grove Schnittstelle

Das mir vorliegende Modul habe ich auf ebay.de für rund 9 € zzgl. Versandkosten erstanden. Du bekommst dieses Modul aber etwas günstiger bei BerryBase für derzeit 8 € zzgl. Versandkosten. Lieferumfang Im Lieferumfang der LED Matrix ist neben der Matrix noch ein kleines Grove Kabel für den Anschluss, sowie ein Zettel mit den wichtigsten technischen Daten.

Auf der LED Matrix ist noch eine kleine Schutzfolie, welche du abziehen kannst, ich lasse diese jedoch drauf.

Aufbau der 8x8 LED Matrix

Auf der Rückseite findest du die Grove Schnittstelle, sowie zwei Lötpunkte für die optionale externe Stromversorgung. Des Weiteren kannst du die I2C Adresse 0x70 via 3 Lötbrücken ändern.

I2C Adressen via Lötbrücken Wenn du die Lötbrücken verbindest, dann kannst du diese Matrix über nachfolgende I2C Adressen ansteuern. Dabei kannst du auch mehrere Muster wählen und so zwischen 8 I2C Adressen auswählen. Verbundene PinsI2C Adresse-0x70A00x71A10x72A20x72A0 & A10x73A0 & A20x75A1 & A20x76A0, A1 & A20x77 Zur Ermittlung der I2C Adressen habe ich den I2C Scanner von https://playground.arduino.cc/Main/I2cScanner/ verwendet.

Zusätzliche Ressourcen für die Programmierung am Arduino

Damit du diese LED Matrix programmieren kannst, benötigst du entweder - ein Grove Adapterkabel, oder - ein Grove Base Shield für den Arduino UNO R3, oder - ein Seeeduino Nano

Grove Adapterkabel zu Breadboardpins

Grove Base Shield für den Arduino UNO R3

Seeeduino Nano Das Grove Base Shield hat mehrere Grove Buchsen digital & analog und somit bietet dieses eine sehr große Bandbreite an Möglichkeiten für Projekte. Wenn du lediglich die LED Matrix programmieren möchtest und du hast bereits einen Arduino Nano oder Arduino UNO dann

Programmieren der LED Matrix am Arduino via I2C

Damit die LED Matrix mit HT16K33 Treiber angesteuert werden kann, müssen wir in der Arduino IDE eine zusätzliche Bibliothek installieren. Diese können wir uns als ZIP-Datei vom GitHub Repository Seeed-Studio/Grove_LED_Matrix_Driver_HT16K33 herunterladen. Weitere Informationen zu diesem Modul findest du auf der englischen Wikiseite von Seeedstudio https://wiki.seeedstudio.com/Grove-LED_Matrix_Driver-HT16K33/. Anzeigen eines Smileys auf der LED Matrix Für die Erstellung eines Smileys kannst du den LED Matrix Editor unter https://xantorohara.github.io/led-matrix-editor/ verwenden. Dieser Onlineeditor gibt dir die Möglichkeit, mit der Maus auf der LED Matrix einzelne LEDs zu aktivieren / deaktivieren.

LED Matrix Editor von Xantorohara Auf der rechten Seite findest du ein Stück Code, welchen du in dein Arduino Programm integrieren kannst. In meinem Fall habe ich ein lachendes Smiley gezeichnet und erhalte den Wert "0x3c4299a581a5423c". Die Bibliothek liefert zusätzlich ein paar Beispiele, welche mit der default I2C Adresse 0x70 lauffähig sind. Von diesen Beispielen wähle ich zunächst "displaycustom_pictures" und modifiziere dieses etwas. //Bibliotheken zum kommunizieren mit der LED Matrix #include #include "Grove_LED_Matrix_Driver_HT16K33.h" //Wert für ein lachenden Smiley const uint64_t smiley = 0x3c4299a581a5423c; //instanz einer LED Matrix Matrix_8x8 matrix; void setup() { //beginn der I2C kommunikation Wire.begin(); //beginn der kommunikation mit der LED Matrix matrix.init(); //setzen der Helligkeit der Matrix //Werte sind zwischen 0 und 15 //wobei 0 dunkel ist und 15 das hellste matrix.setBrightness(5); //In welcher Frequenz die LED Matrix blinken soll, //Werte sind: //- BLINK_OFF > kein blinken, //- BLINK_1HZ > langsames blinken, //- BLINK_2HZ > schnelles blinken, matrix.setBlinkRate(BLINK_OFF); } void loop() { //anzeigen eines Bildes matrix.writeOnePicture(smiley); //absenden der Daten matrix.display(); //eine Pause von 10 Sekunden delay(10000); } Auf der Matrix hat man natürlich nur begrenzte Möglichkeiten zur Darstellung von Bildern, jedoch für so kleine Smileys und Pfeile ist dieses bestens geeignet.

lachender Smiley auf der 8x8 LED Matrix Ausgabe von Scrolltext auf der LED Matrix Da wie erwähnt die kleine LED Matrix nur begrenzten Platz für Zeichen bietet, gibt es die Möglichkeit Text auf diesem durchscrollen zu lassen. void loop() { //Funktion zum anzeigen eines Textes auf der LED Matrix, //Parameter: //String - die Zeichenkette welche ausgegeben werden soll, //Zahl - Wert in Millisekunden pro Zeichen //Typ //ACTION_SHIFT - jedes Zeichen einzeln anzeigen, //ACTION_SCROLLING - den Text durch die Matrix scrollen lassen matrix.writeString("Hallo Welt!", 1000, ACTION_SCROLLING); matrix.display(); } Damit ich das Video aufnehmen konnte, sodass meine Kamera den Text erfasst, habe ich ein kleines Tuch vor die LED Matrix gehängt.

Ändern der default I2C Adresse im Programm

Wenn du bereits Sensoren oder Aktoren am I2C Bus angeschlossen hast, dann kann es vorkommen, dass die default I2C Adresse der LED Matrix bereits belegt ist und du diese im Programm überschreiben musst. (Oder auch, wenn du mehrere solcher Matrixen an einem I2C Bus anschließen möchtest.) Dazu findest du in der Funktion setup den Aufruf der Funktion "matrix.ini();". Diese Funktion kann einen Parameter vom Typ uint8_t übernehmen und hat als default den Wert des Feldes HT16K33_DEFAULT_I2C_ADDR. #define HT16K33_DEFAULT_I2C_ADDR 0x70 Wir übergeben also nun den Hexadezimalen Wert, welchen wir aus der Tabelle (siehe I2C Adressen via Lötbrücken) entnehmen können. Und brauchen quasi in unserem Programm nichts weiter anpassen. matrix.init(0x71);

Vergleich zwischen 8x8 LED Matrix - MAX7219 & HT16K33

Zum Schluss möchte ich dir noch gerne die Unterschiede zur LED Matrix mit dem MAX7219 Chip aufzeigen. Diese LED Matrix verfügt ebenso wie die vorgestellte Matrix über 8x8 LEDs und kann ebenso einfach programmiert werden.

8x8 LED Matrix mit HT16K33 Treiberchip

8x8 LED Matrix mit MAX7219 Treiberchip Jedoch kannst du diese Matrix zu mehreren zusammenstecken und so eine schier endlose Anzeige aufbauen.

MAX7219 Shields auf einem Stativ Die LED Matrix mit Grove Schnittstelle jedoch kannst du nicht so kaskadierend aufbauen und somit bist du mit dem Modul in deinen Möglichkeiten stärker beschränkt.

Fazit zur Programmierung der 8x8 LED Matrix mit Grove Schnittstelle am Arduino

Die LED Matrix von Seeedstudio mit Grove Schnittstelle und HT16K33 Treiberchip lässt sich super einfach programmieren. Du benötigst wenig Code und über die I2C Schnittstelle und dem Grovekabel hast du deutlich weniger Verkablung als bei der LED Matrix mit MAX7219, leider vermisse ich hier die Möglichkeit die Module kaskadierend zu verbinden und so ein langes Display für Laufschrift aufzubauen. Mit dem Online LED Matrix Editor kannst du dir jedoch recht einfach kleine Frames für die Matrix erstellen und in den Code kopieren. Ausblick Ich werde nun mal schauen, welche kleinen Projekte man mit dieser Matrix aufbauen kann. Jedoch würde ich eher zu einer RGB Matrix tendieren, denn diese kann bei gleicher Baugröße verschiedenfarbige Pixel anzeigen. Read the full article
