I just did it to mine and am very happy the way it turned out. Also, i now that someone mentioned about taking very fine sandpaper and sanding the traces on circuit paper. I had to do that. I went out and bought 6 new bulbs and it turned out that i only had 2 bulbs that were blown. The sockets were the problem. What I did to fix that was sand them as well. There are 2 tabs that actually make the contact with the circuit paper, I sanded those. I also sanded the inside where the actual bulb makes contact with the socket tabs. Good luck. Hope this helps.
