Abstract
A motor vehicle lighting device has a housing and a ventilating device with an air supply line, which has an air intake opening, and which tapers away from the air intake opening in the form of a funnel, and which has an air outlet opening. The ventilating device includes a water collecting chamber, into which the air supply line opens with a transition cross section, and which has a water discharge opening and an air outlet opening, wherein the water discharge opening is disposed lower than the air outlet opening in an intended use of the ventilating device in a motor vehicle. A clearance of the water collecting chamber lying between the transition cross section and the air outlet opening is greater than the transition cross section.
