Abstract: A portable cassette tape illuminator is disclosed having a small light which is meant to be attached to items used in the dark such as a cassette tape player. The portable cassette tape illuminator consists of a small light bulb, small battery, electronic circuitry, two thin wires and a "touch" on/off switch. To utilize it in a cassette tape player, place the bulb end into the left side of the cassette tap receptacle and string the wires up to the player control buttons where it may be looped.
