There are lights located under the helm in the Lazarette. These lights light up under the water. The part on the picture didn’t exist before. It came from the will of protecting them from damage, water, or oil. The captain wanted some housings made that could come off easily so he could still service the lights.
They went for a simple and robust design. The parts needed to be strong and out of sight. There were needs to have vents to disperse the heat and a base that the housing could attach to, so the design incorporated these features.
The material choice was PA-CF for its mechanical strength since there may be cargo falling and hitting them – or people stepping on them. In addition to its strength, carbon-fiber-reinforced Nylon has a resistance to chemicals like engine oils, fuels, or cleaning chemicals that could be found in the vicinity.
