A rapidly directional assembled and water-proof lamp comprises a bulb, a washer, and a seat. The bulb has a casing connected to a flat engaging portion, and each surface of the flat engaging portion is installed with a trench and a longitudinal groove. A flat groove is formed in the seat with two opposite outer walls. Each wall has a transverse block and a longitudinal strip at position with respect to the trench and longitudinal groove of the flat groove. Thereby, the bulb is directionally engaged with the seat; and a front opening of the flat groove has a toggle. An annular flange is formed below the toggle so that the bulb and seat are engaged. The annular flange and the toggle buckle a cambered portion of the bulb; and thus, by the elastic force of the annular flange and the washer, water will not permeate into the bulb to induce a short circuit. Therefore, a bulb with functions of rapidly directional assembly and water-proof is formed.
