A lighting equipment includes a cylindrical tube having a profile formed in a bottom. The profile has a pair of lower grooves and a pair of higher grooves. A barrel, a spring, a cell and a braket are received in the cylindrical tube. A rod is coupled to the bracket. A pin is laterally provided on the rod. The pin is actuated to follow the profile so that the pin is laid in either the upper grooves or the lower grooves. A center electrode of the cell is actuated either to contact or to be separated from a prong of a light bulb in order to turn on or turn off the light bulb. |
