A light strip system comprises an elongate carrier arrangement formed by mounting rail elements that are open towards the lower face, a shaped part which consists at least partly of a flexible material and forms an accommodation space formed in the carrier arrangement and extending in the longitudinal direction, and a lighting module component arranged in the accommodation space. In order to hold the lighting module component it is arranged so as to push against contact regions of the carrier arrangement, on two opposite sides, each time with the interposition of regions of the shaped part.
