You could also remove the existing pieces and spray paint them.
Use masking tape to protect the back and remove the LED. Glue it in place after the painting is done. Remove the button and be sure to cover the part with the mounting holes with tape.
I used Krylon high-gloss black (already had a can of that) and a matte clearcoat from a home improvement store. The clear coat was about $3.50 USD. It took about 2 days to get good results. I put the pieces on newspaper in the back yard and would give them light coats of paint until they looked complete. Start spraying at the paper and move the spray in a continuous motion across the pieces. Use multiple, light coats. Don't stop the motion or try to do it all at once. That will create uneven liquid glop. At some point, you'll think they're totally black. Compare them next to something truly solid black with indoors light to make sure. Finish with a few light applications of clear coat.
The result looks better, in my opinion, to a black bezel with white logos on it. I did it while I was watching TV and doing chores around the house so a few trips to the backyard weren't any real hassle.
