Darkened rear tail lights

So I was looking at my tail lights as I was walking up to my Sportsman and I got to thinking about how they may look darker given that my atv is mostly grey and black. So I went up to the part store and purchased some "VHT Night shade" spray. I decided to tape around the part that bulges up to kind of give it an evil look as if it has eyes and this is the result, thoughts?
