The spotlight uses two elbow-shaped housings (an inner housing and an outer housing) in the spotlight assembly.

• Functionally, the housings must block penetration of moisture, dirt, and dust into the gear mechanisms and electrical system. 

• The housings and the external support shaft also act as the ground for the electrical circuit. 

The housings must have a smooth, reflective chrome-plated finish for appearance and resist denting, pitting, corrosion, and abrasion.
