These dots on the side of the rotating platform of the turntable have a light shining on them. The light must be exactly on the dots, which means the record is at the exact RPM it is supposed to be. If the light is moving in front or behind the dots, the record is not going at the right RPM.

RPM, or revolutions per minute, is the number of times an object completes a full 360 degree rotation in a minute. This is the speed vinyl records are measured at.
