i did it to mine. i sanded the lights w/ 600 grit paper and sprayed them with "window tint" paint, or trasparent black. then i used rubbing compound and rubbed off the paint on the reverse light part and rubbed some of it off down the center of the light so the edges would be darker. dont make it too dark though, because then your lights are hard to see. then if you want, you can clear coat the whole thing to keep it from fading. i would post pics, but mine started fading because i didnt clear coat it, so i just took it all off.
