lightsd runs under the `lightsd' user and group by default; add yourself to
this group to be able to open lightsd's socket and pipe under /run/lightsd:

  gpasswd -a $USER lightsd

Re-open your current desktop or ssh session for the change to take effect.
Then use systemctl to start lightsd; you can start playing with lightsd with:

  $(lightsd --prefix)/share/lightsd/examples/lightsc.py

post_remove() {
    getent passwd lightsd >/dev/null && userdel lightsd
}
