one of your headlights is out, and I used chrome paint, their is a website you can get a chrome side marker especially for the lincoln ls, not a plastic paint job, but It's not worth it I'd say just go with chrome paint or if anything just buy some chrome tape somewhere, it's more like a tint, u cant see the leds during the day but at night they light up threw the chrome and it looks awesome, I think it blends the car color alot better, and because your's is silver I can imagine it would blend alot more, I'd say go for it
if u want the website for an actual chrome side marker I can give it to u, but i tell u, they won't gaurantee a perfect color-toned match of chrome with the rest of the car, so I wouldnt waste 100$ on that.
also I jus washed her today to see if anything would wash off or anything but nope she still shines, good luck!
