A new POP-IN BULB for INSERTING AND REMOVING A LIGHT BULB WITHOUT NEED OF TWISTING AND SCREWING. The inventive device includes a cylindrical casing having an open upper end, a closed lower end and a cylindrical side wall therebetween. A pair of vertically disposed springs are secured to an interior surface of the closed lower end of the casing at a central location thereof. A pair of generally L-shaped support brackets are positioned in a facing relationship and are pivotally secured to an interior surface of the cylindrical side wall of the casing a diametrically opposed relationship. The support brackets are spaced so as to receive a base of a light bulb therebetween. A pair of cam levers are provided having an electrical contact disposed therebetween. The cam levers are coupled with the vertically disposed springs with the electrical contact positioned between the vertically disposed springs. The cam levers are in contact relationship with lower extents of the L-shaped support brackets in a working orientation. A pair of power wires are coupled with the electrical contact and with one of the L-shaped support brackets.
