Night flying is great fun. Radio is usually a lot quieter and generally it's much smoother.
A couple of things to remember/consider. Take a bit more time out to look at the forecast and Metars. Note if the temperatures quoted are the same or close together. This means that there is a very good chance of the vis falling. Note when the tempo's are for and add a decent buffer to them. The vis can be hampered at dawn/dusk when there's just enough light to see but it can mask the runway lights if it's a bit misty/foggy. (That has happened to me).
Make sure you do carry enough fuel to go to an alternate as well. (I know legally you have to but keep an eye on it as that field may go "under" regarding the wx too).
If you have a spare moment when you are flying, listen out on the atis's and volmets to keep yourself in the picture as to how the wx is going.
Carry a spare torch and make sure it's working too.
Enjoy.
