many of you must have notice that various manufacturer of power tool be `` give away '' flashlight with cordless drill , etc. . well , this be how they make money , by charge $ 5 for one flashlight bulb ! what a ripoff . in my experience , these light bulb be cheaply manufacture and blow out in matter of week , not year . I recommend that you search for `` 4-led flashlight '' on Amazon.com and , for a bit more money , buy one of these lead model for which you never have to replace the bulb .
