Abstract

The invention relates to a vehicle light (24) having a housing (9), a cover pane (13) covering a light emission area of the housing (9), at least two chambers (12, 22) disposed one above the other and each having an intermediate light pane (11, 21) positioned at a distance, at least one light source (1, 3, 8), and a reflector (2, 4, 7) associated with the light source (1, 3, 8), mounting means for mounting on a vehicle body, and a defogging device inducing at least one air flow by the heat generated by the at least one light source (1, 3, 8). According to the invention, the defogging device comprises at least one means (2, 4, 4`, 5, 7, 25, 27, 28) directing the air flow, at least one means (10, 14, 16, 10, 19, 20, 23) guiding the air flow, and at least one light source (1, 3, 8) generating heat and having an associated reflector (2, 4, 7) and an associated intermediate light pane (11, 21), the at least one means (2, 4, 4`, 5, 7, 25, 27, 28) directing the air flow having at least one air flow divider (25, 27) for dividing an air flow induced by convection heat into at least two partial air flows (6, 26, 32).
