A lighting device comprising: a shell; a first circuit; a light source set in the shell; an axis mounted in the shell; and an effective amount of conducting liquid. A rotation device and a switch device are rotatably connected to the shell via the axis. The switch device comprises a first storing cavity and a second storing cavity, which is configured for accommodating the conducting liquid. The first storing cavity communicates with the second storing cavity. A plurality of pairs of third grooves is formed in the first storing cavity. Each of which is set a pair of positive/negative terminals. Each of the pairs of positive/negative terminals is electronically connected to light source and the first circuit. A slide bar is formed on the rotation device, and is configured for pushing the conducting liquid inside of the first storing cavity.
