What "bulb" did you use? If you bought the bulb and holder from the site that's advertised on this site (popular search), the holder does not line up correctly (the bulbs wire "legs" do not make contact).
I bought 5, then carefully removed the bulbs from their base they came with, and placed the bulbs into the original socket. I had to do this for the main switch, the 4x4 switch, and the fog light switch.
If I had to do it over again, I would have gone with LED bulbs.
