Glimmer indicates a nondirectional light that is feeble and unsteady: a faint glimmer of moonlight. Beam usually means a directional, and therefore smaller, stream: the beam from a searchlight. Ray usually implies a still smaller amount of light than a beam, a single line of light: a ray through a pinprick in a window shade. 4. shine, glimmer, flash, glitter, sparkle, beam.
