An attachable transversely sliding light including a rod assembly, a holding assembly, a housing assembly and a light assembly is disclosed. The attachable transversely sliding light is mountable onto chairs of all dimensions due to the rod assembly, which extends and retracts to cooperate with chairs of various dimensions. At each end of the rod assembly is a holding assembly mounted thereon, which allows the attachable transversely sliding light to be secured onto a chair. Mounted onto the rod assembly is the housing assembly which slides along the length of the rod assembly to position the housing assembly and light assembly mounted thereon in a position that is optimal to illuminate the user and the surrounding area. The housing assembly houses a battery and has the light assembly extending therefrom. The light assembly can be manipulated into a position that best suits the needs of the user.
