<p>Air intakes (2), usually constituted by N.A.C.A. intakes, are formed in the sides (F) of the motor vehicle immediately in front of each rear light unit (1). When the vehicle is moving, each of the intakes (12) induces a flow of air towards the light unit (1). As it passes through flow-conditioning means, such as a deflector element (4) mounted in a corner position on the light unit (1) or a slot-like duct which passes through the light unit, this flow is transformed into a turbulent air flow. As it spreads into the space surrounding the surface of the light unit (1) and/or flows over it, this air flow prevents the deposition of dirt on the light unit.</p> |
