  • Auto LED dimly lit when off - Electrical Engineering Stack

    NOTE: ''OFF'' is not always an ideal OFF, as this case proves. I had to use diodes often to block leakage currents from electronic modules used to control overhead lights, and sometimes used to trigger a third-party alarm. Often it is a transistor that is not fully OFF simply because of a cheap design.
