Is that not dangerous? I mean it must be hard for the seeker to see the snitch at night. it's hard enough during the day. And the bludger must be also hard to see.

While the bludgers are hard to see its also hard to keep track of who has the quaffle but the snitch has to come back after 15 minutes or so. we practice at night for a reason. because the sun goes down at five and our team captain refuses to make it earlier.
