I find riding at night to be pleasurable, and another advantage is advanced warning of traffic from the other direction IE by the glow of the lights well before you would normally see them in daytime or indeed at dawn or dusk.
all above advice is also duplicated by me.
clean visor is essential and don't forget to take some means of cleaning it as well , in case you get caught in a shower where wagons ETC can readily cover your visor in crud very quickly.
Enjoy the experience
