I took out the entire front left head light assembly today to replace the parking light bulb, but couldn't figure out where it was or how to remove it and insert the new one. My manual includes a picture that doesn't actually correspond to the light assembly on my car (for example, there's only one cap to screw off on the back, whereas the diagram in my manual indicated two). Thanks in advance.

Two should be for a different lighting package, for example xenon

Depends which one you have, if you have corona rings the bulb is screwed onto the back and if you just have a wedge bulb, it will have along holder which is turned into the upper section on the back
