A truck bed for a pickup truck includes a metal support structure that is in a fixed position relative to a pickup truck. A light transmissive cover is disposed over the at least one light emitting die. The unit memory cell may include a fuse and an anti-fuse in series with each other or may include a vertically oriented fuse. The second component receives a service response from the first component; the service response specifies counter-proposed parameters relating to a proposed level of coupling between the first component and the second component.
