Abstract

The invention provides a traffic light (1). The apparatus includes a light source (2) contained in a housing (3) and a reflector (11) to direct light at a position spaced apart from the source. The housing is planted in the ground (8), preferably cemented in the pavement. The reflector is conveniently a suitably arranged object with a reflective surface. The support (10) extends upwardly from the housing providing a conduit arranged so that the source projects light upwardly through the support to the reflective object. From here the light is directed through a lens (14) in an opening- in the support. The light source is an array of light emitting diodes (LEDs). In a preferred embodiment, three such arrangements are provided together as a traffic light assembly which switches between green, amber and red light signals in the usual way. The upright support is removably securable and relatively inexpensive. All the working components are protected in the housing. The traffic light also poses a reduced risk should a motor vehicle collide with it. A damaged support can be easily replaced using suitable fastening means.
