Abstract: A flashlight with multi-brightness levels comprising a body structure, which comprises a body and a head cover screwing onto each other. There is a hollow compartment, where batteries are placed in the body structure. The head cover screws onto the top of the body structure. There is a lighting device, which comprises multiple sets of light bulbs placed in the interior on the top of the body structure. There is also a forward contact device, which comprises at least one set of separatable upper and lower conductors placed in the interior of the body structure and under the lighting device. The forward contact device also comprises an axel, which joins into the conductor device. When screwing the body structure and the head cover, the movement activates the axel contacting the battery. Furthermore, the axel lifts the conductor device, so that the upper and lower conductors separate or contact each other. The spring device comprises multiple springs opposite to the light bulbs of the multiple lighting sets.
