Abstract: A system may have a support structure that separates an exterior region from an interior region. The system may include a lighting system with interior and/or exterior lights with adjustable diffusers. An interior light may be used as a task light, a cabin light, a sensor indicator light, or a trim light. Adjustments to the adjustable diffusers can be used to adjust the angular spread of emitted light for operation in different lighting modes.

Abstract: A brace member having a longitudinally extending tapered body portion includes a first end portion having an expanded head of a frusto-conical shape terminating in a planar surface and a second end portion having a U-shaped member secured thereto. The planar surface of the expanded head is positioned in an abutting relation with a supporting structure, such as the metallic superstructure of an oceangoing vessel. The conical shape of the expanded head forms with the surface of the supporting structure an annular recess for receiving a weld to unite the end of the brace member securely to the supporting structure. The U-shaped member includes a semicircular base having means for securely receiving and retaining a pipe, conduit or the like in a fixed position relative to the supporting structure.
