This invention is about a screwdriver with an indicator bulb. There is a U-shaped fixation base on the front part of the handle of the screwdriver. Inside the fixation base is a semi-circular ring for the fixation of the indicator bulb base. In front and below the bulb base have a longitudinal slot and a mating semi-circular hole. Inside the slot and the hole is a rectangular slot for insertion and fixation of a LED bulb. In the middle of the rectangular slot is an embedded slot that allows connection to the battery container behind. A LED diode cable will pass through the embedded slot and go to the positive and negative electrodes of the battery in the battery container, supplying power for the indicator bulb, which provides illumination parallel to facilitate the screwdriver lock up operation. The bulb is turned on/off by pressing a press button.
