Abstract
A digital tool with a light display comprises at least one light display assembly. The light display assembly includes four or more light-emitting elements to cooperate with a light-transmitting element. The light display assembly can be the whole or a part of a handle sleeve. Therefore, by cooperating with a compare unit and a control unit, under the predetermined condition, the light-emitting elements can emit light through the light-emitting area synchronously or alternately.
