PCT No. PCT/GB94/01483 Sec. 371 Date Apr. 8, 1996 Sec. 102(e) Date Apr. 8, 1996 PCT Filed Jul. 8, 1994 PCT Pub. No. WO95/02783 PCT Pub. Date Jan. 26, 1995A motor vehicle headlamp has a dished housing (10) in which a light source is located and which is closed at its front by a light transmitting cover. A ventilation passage (16, 26, 30) provides communication between the interior and exterior of the housing. The ventilation passage is defined by a tubular portion (12) extending from the housing (10) and by a cap (20) mounted on the tubular portion (12) so that an end wall (28) of the cap (20) is spaced outwardly from a housing-remote end of the tubular portion (12). The tubular portion (12) has a continuous side wall. The end wall (28) is joined to mutually spaced lateral walls (24) of the cap (20) whereby there is defined a downwardly opening slot (26) forming part of the ventilation passage (16, 26, 30). The end wall (28) of the cap (20) projects downwardly beyond lower edges of the lateral walls (24) of the cap (20).
