Lil trick for ya i did to mine, get someone who can spray to get some basecoat colour of your choice (i used panther black as it was the colour i sprayed mine!) and put a small amount into some laquer, not loads but the more u use the darker it will be!!!

Then with the lights key'd up just spray them and job done, looks loads better than those shitty tint cans as the laquer gives it a nice shine

This is how they look, will work with any colour and alot cheaper than buying a set of aftermarket ones Plus with metallic paint in it you get a nice glint to it under lights or sunshine!!
