This handy carabiner clip keychain light features surface mounted technology (SMT), which provides a much stronger illumination than LED bulbs. The device features one SMT strip activated by push-button and three light modes: bright, dim, and strobe. The device also includes a magnet on the back for mounting. Measuring 3" x 2" x 1", the keychain will clip unobtrusively to belts or purses, and will easily fit in any pocket.
