Abstract: A tape measure light attachment which can be deployed on the extended measuring tape of a tape measure for illumination purposes may include an assembly housing. A light assembly may be provided on the assembly housing. The light assembly may be selectively configurable to emit light upon activation. A mount assembly may be provided on the assembly housing. The mount assembly may facilitate attachment of the assembly housing to the measuring tape. A hook assembly may be provided on the assembly housing. The hook assembly may be configured to facilitate engagement of the assembly housing with a retaining structure to retain or immobilize the assembly housing on the measuring tape as the measuring tape is extended from the tape housing of the tape measure to measure a length or distance from the point of engagement between the hook assembly with the retaining structure and the tape housing.
