The arrangement has at least 2 crossed light waveguide arrangements (12,13), the first in a gap between 2 parts (14,15) of the second so light emanating from one end of the first part of the second arrangement passes at least partly through the first arrangement before entering the end of the second part of the second arrangement. The outlet end cross-section (16) is greater than that of the inlet end to reduce or prevent cross-over damping. AN Independent claim is also included for the following: a light waveguide.
