The price and performance of LED lighting have reached the point where LEDs are displacing more traditional lighting. Even though LED lifetimes are as high as 50,000 hours, they are still being designed as replaceable bulbs rather than being integrated as a permanent part of the lighting assembly. The invention provides for a means of economically producing laminated glass with integrated LED lighting designed to last the life of the vehicle. This is done by embedding the LED die into the plastic layer used to bond the glass layers of a laminate together, forming an embedded wire circuit from thin high tensile strength Tungsten wire to power the LEDs and by utilizing machine tool technology originally developed to produce integrated circuit assemblies such as RFID ID cards, tickets and passports.
