The light strip at the top of housing and the LEDs going around the ring of headlight is out. Do I really need to replace the whole assembly or are there replacement bulbs to restore lighting versus buying whole assembly?

Hi, it is not possible to diagnose your vehicle from a distance. If in fact the lights within the headlight housing are inoperative, and it is not a connection problem, then the entire assembly would need replacement. If you are unsure about a proper diagnosis, we suggest that you take your vehicle to a professional repair shop.
