    When lights blink fast, it makes it hard for people to drive cars and see where they are going. The faster the lights, the harder it is to see. There's a new way to make lights that don't do that anymore.

  • Surge protection

    A surge protector is a thing that protects your stuff from going kaput. Without it, your stuff can get messed up if there is a big zap of electricity, bye-bye!
