A fastener assembly includes a grommet, a dampening subassembly, and a pin. The vehicle lighting unit can project light outwardly through an opening portion formed in a mirror housing of a sideview mirror along a vehicle length direction and near an outer side of the sideview mirror in a vehicle width direction. One or more of the semipermeable membranes of the system may be initially sealed by an overlying impermeable membrane upon implantation of the system into the patient. The process further comprises depositing a second layer on said first layer. The compounds according to this invention possess anti-cell proliferation activity and show an increased plasma-stability.
