'06 A4 Curve Tracking Headlights
 

Having issues with wiring degrading in housings - insulation peeling and shorted causing day lamps to not work/alarms in car. Main HID lights and directionals still working (for now). Replacement assemblies available for $500+/each. Looking for cost effective alternative to keep up reliability of system. Kits available to rebuild units? Will lesser non-curve lights plug and play?
