a lamp body for holding therein a lamp;
a lens mounted on the front of said lamp body; and
a carbon-based heating element mounted within said lamp body and apart from said lamp and said lens,
wherein heat rays radiated from said heating element irradiate a rear surface of said lens, and
wherein the carbon-based heating element does not interrupt light rays from the lamp to the lens.
2. A vehicle lamp according to claim 1 , further comprising a glass tube for sealing therein said carbon-based heating element.
