Abstract: An air venting tube for use with an automobile lamp having a housing formed with an air outlet includes a tubular body, a connecting block and a cover plate. The tubular body has an open first end portion with a front section adapted to be mounted fittingly on the housing at the air outlet so as to be communicated fluidly with the air outlet. The tubular body further has a second end portion with an upper section that extends downwardly at an angle from a rear section of the first end portion, and a lower section having a distal end face with a first circumferential edge part and a second circumferential edge part that cooperatively define an opening. The connecting block is disposed outwardly of the tubular body, and has a planar first end wall with a periphery connected to the first circumferential edge part, and a planar second end wall opposite to the first end wall. The cover plate is formed on the second end wall of the connecting block, and extends in radial directions toward the second circumferential edge part. The cover plate has a size sufficient to cover the opening in the lower section, and is spaced apart from the distal end face by the connecting block to form a clearance with the second circumferential edge part of the distal end face.
