A light stick, primarily useful in the locomotive industry for signally between train personnel, includes a longitudinally extending housing which contains a first light source and a second light source. The first light source provides for general purpose illumination of the light stick. The second light source provides illumination primarily for purposes of signaling. The light stick may include a lens cap which is positioned at a forward end of the housing, and from which the illumination from the second light source may extend. Preferably, the light that is emitted from the lens cap has a blue color for purposes of railroad signaling.
