Headlight Problem, My fault.
 

I was changing out my bulbs last night, the high beams were a piece of cake.
The low beams are where I ran into the problem, and that stupid retaining clip.

Got one bulb in after much struggle, but when I went to do the second one I droped the stupid screw inside the headlight assembly.

How excatly do I remove the whole assembly to get the screw out?

If the screw was steel, go for a magnet on a flexible piece of material to fish it out.

Just leave the screw inside of the light as it will not hurt anything and replace the screw with a new one.

To answer your original question to remove the headlight you have to take the bumper cover off of the car.

Beyond that I agree with oldeng's suggestion.
