My last dealings with the CASA boys in the west was that there should be no open defects on a mr. ie nav light us. Should be written up in clearing endorsement as not required for day vfr flight.
Look in casa maintenance guide for pilots
therefore if a pilot can perform a globe change he is entitled to clear the endorsement.
I believe it’s a odd way to do it as technically it’s still an open defect but who am I to argue.
