Replying to Painting tail lights

So I want to black out the taillights on my VW Golf and I've been told after seeing pictures of blacked out tail lights on someones profile on here a while back that you can do it yourself with spraypaint. Just wondering what is the best way to go about doing this and if there is a particular type of paint that is required. +k for serious answers. I'd really like to do this and if any of you have experience that would be a big help
