This is called 'Traffic Life.'

Tea light and Traffic light combine to light up time in your life.

It consists of 3 colours tea light and one holder for them that looks like traffic light.

Each tea light lights up in a different situation and has a different aroma.

First, red light lights up while you sleep and has a stable aroma.

Because it generally means to stop.

Second, yellow one lights up while you take a break or rest and has sweet aroma

since it normally means slowing down.

The last one is green and it lights up while you work, study or do something hard

and has a aroma that helps you concentrate.

Because it means to go and go ahead.
