When we walk alone on the street in the night of rainy day, it’ s danger because of dark and poor visibility so we could have traffic accident.
“ The Light of The Life ” could let us be noted in the night of rainy day. By the way,
“ The Light of The Life ” may let us feel interested because we looked like walking in a spotlight of our lifes.
The power come from the water battery.
