DIY build your own LED Step lights

Instructables member Quanchante shared an interesting project of building a relatively cheap and pretty darn easy-to-assemble step lights made out of LEDs.
If you are interested then get ready with the following Materials:

•  Glue gun and glue sticks
• Soldering gun and solder
• Felt or Thick fabric that matched the carpet on my existing steps
• 5mm UltraBright LEDs, color: Pure White with clear lens (3 per step light)
• 9v Battery (1 per step light)
• 9v Battery ‘snap on’ terminal leads (1 per step light)
• Sub-mini Slide Switch (1 per step light)
