I have removed the entire light assembly on one side due to a ground wire pilling out of one of my lights when changing the bulb. My lights are vertical on my Aspire, and I can't remember if the Anthem is Vertical or horizontal).
Removing the whole light assembly was not difficult, seems like 3 screws on the bottom of the "light frame" and 3 on the top with a battery drill, unplug the lights, and remove it. (unplug and label the lights first)
I had some images, but can't locate them, but I remember having to disassemble on of the lights to fix the wire, so cleaning the inside of the lens cover, I believe was no problem. I will see if I can find some images
