German user "wasistwahrheit" found out that the new regulation is actually "new light", for this was the previous teaching:
*** g76 11/22 p. 28 Does Christianity Have a Visible Symbol? ***
The Bible, however, sets forth no visible symbol for Christianity. Christians today, therefore, must be on guard not to adopt such a symbol. For example, watchtower-like designs appear on some buildings and Kingdom Halls of Jehovah’s Witnesses. There is nothing wrong with these in themselves. Possibly they may help persons to identify property owned by Jehovah’s Witnesses. However, at no time should anyone look upon such things with reverence, as if they were a visible sign of Christianity.
