Abstract
A vehicle lamp device comprises one thin board-like substrate having an aperture for communicating air from inside the lamp device to the outside of the lamp device, and another thin board-like substrate having a port for air communication. The two substrates are closely adjacent each other and define an air passage therebetween. The air passage is filled with desiccants and communicates air with the interior of the lamp device. The two substrates are located and mounted within the range of receiving sufficient heat from a bulb mounted to a resin reflector.
