Abstract
A vehicle lamp having a front lens with marks formed by irradiating a laser beam on a surface of the lens is disclosed. The laser beam forms the shapes of a mark, and the mark includes recess grooves. Thus, even in cases where the mark is different in displayed content according to the destination of the lamp, for example, and a lamp certification mark must be formed at the same position of the front lens, the mark can be readily formed by suitably performing irradiation control of the laser beam. The method prevents formation of an outline due to a removable mold insert that appears on the inner surface of the front lens and marks formed in a conventional manner in which the removable insert is used to accommodate the changes of the mark displayed content.
