## Abstract

The present disclosure discloses a light fixture and aims to provide a dual-bead rubber-covered string light. According to a technical solution, the dual-bead rubber-covered string light includes a plug, a wire, and light sources, the light sources are connected to the wire, a tail end of the wire is connected to the removable plug, a rubber wire conduit wrapping the wire is disposed on an outer wall of the wire, rubber beads wrapping the light sources by hot melting are disposed outside the light sources, and a ratio of a width of each rubber bead to a distance between the rubber beads is 1/6. The stability effect is strengthened on the basis of an original break-proof effect of the rubber wire conduit, such that the dual-bead rubber-covered string light is not prone to break even in long-term use or when frequently bent.
