A lighting apparatus includes a tubular flashlight with a barrel of a selected size and shape, and a sleeve of uniform cross-section. The sleeve has a through aperture into which the flashlight barrel is engaged with a forward end and a rearward end of the barrel extending from the sleeve. A surface of the aperture has longitudinal resilient ribs. The ribs are of a shape, size, spacing and resiliency as to enable tight gripping of the ribs on the barrel.
