Vibration flashlight

A vibrational flashlight comprising:

• a housing for containing a battery which has a first electrode and a second electrode, said housing comprising a first member on which a protrusion is formed and a second member on which a cylindrical portion is formed, said battery being mounted in said cylindrical portion and bearing against said protrusion such that said battery is firmly mounted in said housing;
• an electrically isolating plate mounted in said housing and comprising a first series of holes formed therethrough and a second series of holes formed therethrough;
• a first electrically conductive line printed on an underside of said isolating plate along said first series of holes;
• a second electrically conductive line printed on the underside of said isolating plate along said second series of holes;
• a plurality of light emitting diodes each comprising a pair of first and second leads, said first leads being inserted through said first series of holes and connected to said first electrically conductive line and said second leads being inserted through said second series of holes and connected to said second electrically conductive line;
• a slender electrically conductive member comprising a first end connected to said second electrically conductive line and a second end resting against the second electrode of said battery;
• and
• a spring mounted in said housing and comprising a first end connected to said first electrically conductive line and a second end which oscillates so as to periodically contact the first electrode of said battery when said vibrational flashlight is subjected to vibration.
