A method for producing lighting devices, comprising at least one lighting module (20). The method comprises the stages of: - providing a plurality of lighting modules (20), wherein each lighting module comprises a first set of contacts placed at a first end of said lighting module (20) and a second set of contacts (204c, 204d) placed in corresponding positions at a second end of said lighting module (20); - connecting together a plurality of the lighting modules (20) for forming a series of lighting modules (20), wherein each lighting module (20a) is connected to the next lighting module (20b) by means of interconnecting elements (10) which connect the first set of contacts of each lighting module (20a) to the second set of contacts of the next lighting module (20b); and - cutting the series of lighting modules (20) in lighting devices comprising at least one lighting module (20), wherein the interconnecting elements (10) of the last lighting module of each lighting device are cut along their transverse axes. In particular, the interconnecting elements (10) comprise a base plate and a hollow portion in order to form female connectors when the interconnecting elements (10) are cut along their transverse axes.
