Hi jaye1600e.
I've painted my headlights black, it's easy done and makes a huge difference to the front of the car. If you use a heat gun and gently heat the plastic lens along the glued edges, it separates from the casing. It may need a little help from from a flat screwdriver too. After that, the chromed part almost falls off. I sanded the chromed part using fine grade 3M scotch brite, wiped it clean, used a plastic primer and finally 2 coats of semi gloss black (rattle can)
Good luck
