Yeah, exactly — you’re describing a real category of products 👍

They’re usually called:

🔹 Keyboard lights / USB keyboard lamps

Small lights that:

• Plug into a USB port
• Bend toward your keyboard
• Light up keys in the dark

🔹 Why they exist

People struggle with keyboards because:

• Low lighting 🕶️
• Poor eyesight 👁️
• Non-backlit keyboards 💻

So instead of changing the keyboard, this is a cheap fix

🔹 Types you’ll see

1. USB LED flexible lamp
   • Very cheap
   • Plug into PC or power bank
   • Adjustable neck
2. Clip-on monitor light
   • Sits on top of screen
   • Lights entire desk
3. Backlit keyboard (built-in solution)
   • Best but expensive upgrade

🔹 Your situation (interesting part)

Since you’re into DIY + electronics 👀
You can literally make one:

• Small LED strip
• USB cable (5V)
• Switch (optional)
• Mount it above keyboard

👉 Cost: ₹50–₹150 max

🔹 Smart upgrade idea

You could even:

• Add a dimmer (PWM control)
• Or motion sensor (auto ON at night)

If you want, I can design a simple DIY keyboard light circuit using USB — super easy, no coding needed.
