Abstract
A vehicle lamp includes a housing having a compartment with an opening. At least one lighting element is mounted in the compartment, defines at least one light output range, and is electrically connected to a circuit board. A transparent cover is disposed in front of the opening of the housing. A thermally conductive member is mounted to a rear face of the transparent cover and has a shape located corresponding to a periphery of the at least one light output range. A front surface of the thermally conductive member abuts the rear face of the transparent cover. A heating element electrically connected to a heating control device is mounted to a rear surface of the thermally conductive member and includes a heating wire having a diameter smaller than a width of the thermally conductive member. The heating wire is longer than the thermally conductive member.
