A light assembly includes a substantially closed housing, a light source, a thermoelectric device, and a moisture expulsion device. The housing is defines a chamber, and includes a lens. The light source is adapted to direct light from the chamber and through the lens. The thermoelectric device includes a cold side and a hot side. The cold side is adapted to form condensation from moisture in the chamber. The moisture expulsion device includes a first segment in contact with the hot side and adapted to receive thermal heat from the hot side, and a second segment in contact with the first segment and exposed to an external environment for dissipation of moisture. The second segment is adapted to receive thermal heat from the first segment, and condensate from the cold side.
