A method for construction a WVPN for a CDMA system is disclosed. Parasitic corners generated based on earlier layout statistics are incorporated into circuit resizing to enable parasitic robust designs. The method includes the serving node receiving data indicative of a group identifier from a given mobile device registered with the mobile telecommunications network. Resistors may be used to provide an electrical connection between the vehicle lights and the vehicle lighting system even if they are not to be illuminated by the system.
