2001 BMW X5 Head Light

The headlamp assembly is retained with four screws, there are two at the core support on top and easy to see, two down low inside the engine compartment, look for the mounting tabs and all are 8mm hex head. I usually use a magnetic socket to retrieve the lower ones. Wiggle it out and be aware of the lower trim insertion at the paint matched lower trim on the headlamp assembly. The tail lamp assembly may need replacement if there is heat damage and/or corrosion/pitting in the conductive plate that the bulb holders sit on and that bring power to the bulb holders, or perhaps just a new bulb holder alone. You might need to remove the tail lamps from the car to properly inspect them, there are three 8mm nuts retaining them, easy to get them out, let me know!
