Abstract
Lamp assemblies for reducing headlamp condensation are disclosed. One example lamp assembly includes a lamp housing including a front housing and a rear housing forming a lamp cavity; a light source extending from the rear housing into the lamp cavity; a reflector extending around the light source; and a duct extending between the rear housing and the reflector from the light source to a remote section of the lamp cavity spaced from the light source. The duct can include a duct cavity configured to draw air from the remote section of the lamp cavity toward the light source to reduce condensation in the lamp cavity.
