Vented automotive lamps exchange moisture with the surroundings during steady state and transient conditions. An application of Fick's Law of Diffusion gives the mass transfer rate of a vapor A through a stagnant column of gas B for steady-state conditions. Automotive lamp ventilation is similar to this simplified problem given certain assumptions and where the vapor A represents moisture in the air at one end of the vent tube and the gas B is the air in or outside the lamp. This paper shows that the equimolar counter-diffusion problem, a solution for Fick's Law, has potential in reliably predicting humidity changes within an automotive lamp for static conditions.
