A lamp ribbon is made of a number of lamp units fixed to a belt construction. The belt construction is made of an upper belt layer and a lower belt layer, each generally formed as a strip and made of a flexible electrically insulating material, which are laid against and fixed to one another, and also includes two strip shaped conductors which are laid between the upper and lower belt layers in parallel and are sandwiched therebetween. Parts of the lower belt layer at a number of places are absent, so as to expose the two conductors for a certain distance at each of these places, and at each such place a pair of apertures are formed through the upper belt layer between the two conductors. Each of the lamp units includes a bulb socket abutted against a part of the outer surface of the upper belt layer opposed to one of the places where the lower belt layer is absent. The bulb socket has a pair of terminals which protrude from it, and each of these terminals passes through one of the corresponding pair of apertures in the upper belt layer and then is bent over and soldered to one of the conductors. A bulb is detachably mounted to the bulb socket, and has a pair of terminals each of which is electrically connected to one of the terminals of the bulb socket.
