A light strip assembly having an elongate light strip with a number of longitudinally spaced-apart miniature lights, for example pre-focused LED's, mounted to the strip. The light strip assembly is detachably mounted to the base member so that light from the miniature lights on the light strip is directed downwardly through the downwardly facing opening when the lights are lit, the light strip assembly being mounted to the base member so that the light strip assembly can be selectively adjusted through an angle of about 60.degree. to enable selective adjustment of the direction of light from the light strip assembly. A diffuser lens may be detachably mounted to the base member so that the lens is in the path of light from the light strip assembly when the lights are lit.
