A lighting system capable of reducing a number of components and cost is provided. A back substrate, a lamp body including front support columns that guide and position the back substrate when the back substrate is attached, and a front substrate that is disposed in the lamp body to be stacked on the back substrate and is fixed to tip end portions of the front support columns are included. The front support columns perform guide and positioning of the back substrate, and fixing of the front substrate, and thereby the number of components and cost of the lamp body are reduced, as compared with a case where the guide portions, positioning portions and fixing portions of the back substrate and the front substrate are individually provided respectively.

A head lamp for a vehicle including a moisture removing apparatus may include a moisture removing apparatus, moisture generated in the head lamp is removed by a moisture absorbent, wherein the moisture absorbent is dried, such that moisture absorbing performance of the moisture absorbent is restored, continuously maintaining a smooth moisture absorbing function. In addition, the moisture generated during drying the moisture absorbent is not again introduced into the head lamp, but is discharged to the outside, blocking the moisture from being generated in the head lamp.

A heater is provided for a vehicle illumination assembly. The heater includes a heat transfer body, a heat source, and a mounting base. The heat transfer body has a top surface and a bottom surface. The top surface has a higher emissivity than the bottom surface. The heat source is affixed in heat transfer relation with the heat transfer body. The mounting base is configured to affix the heat transfer body within a housing of a vehicle illumination assembly to provide the top surface of the heat transfer body in radiant heat transfer relation with a light transmissible portion of the vehicle illumination assembly. A method is also provided.

A lamp chamber (110) includes: a first lamp chamber (110A) located in a forward direction from a first reference plane (P1) and inwardly of a second reference plane (P2) in a width direction of a vehicle; and a second lamp chamber (110B) located in a rearward direction from the first reference plane (P1) and outwardly of the second reference plane (P2) in the width direction of the vehicle. A headlamp (101) includes: a first vent member (105) attached to a first opening portion (102A) provided in a region of a housing (102) facing the first lamp chamber (110A); and a second vent member (106) attached to a second opening portion (102B) provided in a region of the housing (102) facing the second lamp chamber (110B). The vent members (105, 106) each include a waterproof air-permeable body. The air permeability value of the first vent member (105) is higher than the air permeability value of the second vent member (106).
