<p>The invention relates to a road signal which is used to protect against and prevent accidents that could be caused by vehicles parked on a public thoroughfare, road or motorway for emergency reasons. The invention is characterised in that it comprises a series of concentric rings which are made from a reflective material and which are interconnected by means of rectangular sections of the same material, said rectangular sections forming a cross. The central ring comprises a central cavity which is used to house a mica-covered light source. The light source comprises a rear switch with three positions: off, permanent light and flashing light. The outer ring comprises a rectangular coupling projection. The aforementioned coupling sections between the concentric rings comprise a rear rectangular relief which is also in the form of a cross and which contains the rear part of the concentric rings. Moreover, the relief contains a base consisting of four arms which also form a cross and which are positioned diagonally opposite one another around a circular sections comprising an upper, central, rectangular groove. Said base is separated manually in order to be connected to the rectangular coupling projection of the outer ring, using the central, rectangular groove, so that it can rest on the ground.</p> |
