A light combined with a cable illuminates a cable-stayed bridge in which a deck slab is fixed by a cable, or a structure in which wires or cables are combined, so as to achieve improved visual landscaping effects. The light of the present invention comprises a frame (110), a lamp (120), a housing (130), and a switch (150). The frame (110) comprises: a through-hole (111) for the a cable (13) to pass therethrough; a plurality of lamp mounting grooves (112) formed along the circumference of the through-hole (111); and fastening holes (114) which are formed along the circumferential surface of the frame and communicate with the through-hole (111) in the horizontal direction, and each of which has an inner surface provided with a female screw thread. The lamp mounting grooves (112) are formed into steps such that lamp mounting grooves closer to the through-hole (111) are deeper than those farther away from the through-hole. The frame (110) further comprises a bar-shaped first fastening bolt (116) which passes through one of the fastening holes (114), and which has a circumferential surface with a male screw thread so as to engage with the female screw thread. The lamp (120) has light sources (121) fixed in the respective lamp mounting grooves (112) to emit light. The housing (130) accommodates the frame (110). The switch (150) controls the flickering operation of the lamp (120), and is installed within the housing (130).
