No the gauges come with everything you need, however I highly suggest buying the brass tubing kit for the mech oil gauge. Personally I don't trust the thin nylon tubing they give you. It crimps easy and could tear. You may have to buy some wire, crimps and crimp tool, and I would suggest an AG (automotive glass) inline fuse holder and fuse. One for lighting, one for the electric gauges you put in
The gauges do light up at night, but they just have a 194 bulb in them. It's basic, simple, old fashoined side lighting like cars had in the early 80's and earily. Sometimes they can be a little hard to see, but they do work.

Take a look at autometer's site. Gauges like the Carbon Fiber, Phantom, Ultra Lite and so on are "side lit" they lite with a 194 blub. Gauges like the NV, Nexus, Ultra Lite II are lit with LED type lighting. Pretty much like the clusters in today's cars.
Figure out what you want gauge wise, and then see if they have what you are looking for, in the style you like.
