A traffic beacon apparatus has an upper portion comprising a panel member which is attached in an upright position by coupling member to base pedestal. The coupling member is a hollow shell structure formed of an elastic material. The panel member attaches to a top of the coupling member by bolts and barbed projections which are inserted into slots in the top of the coupling member. The coupling member has a flange along a lower perimeter thereof which couples with the base pedestal. The elastic material of the coupling member is more flexible than the panel member which is formed from a relatively stiff material. Apertures are formed in opposing sides of the coupling member to define a bending portion. Sides of the coupling member disposed between the apertures flex and bend when the traffic beacon is struck by a vehicle. Due to the elastic nature of the coupling member material and the positioning of the apertures, the coupling member permits the panel member to be bent down in a collision and then return to the original upright position. |
