2 letter designators for airfields still exist in some places, mostly military airfields.
As for 'pundits', there are 4 styles of lights used in the UK:
Aerial Lighthouse.
There is only one remaining Aerial Lighthouse in the UK and this is situated on the top of the RAF College at Cranwell. It is a lighthouse operated by Trinity House and consists of a rotating white light.
Identification Beacon. (aka 'Pundit')
Flashes 2 letters in morse code through 360 deg corresponding to the airfield designator in red for military airfields or green for civil airfields.
Location Beacons.
1) These flash alternately either white and green (civil airfields) or white and red (military airfields) but there is no morse code letter however examples I have seen may consist of a double ended rotating light which thus show the different colours alternately.
2) At some civil locations, the 2 colour beacon may be replaced by a flashing white strobe light showing through 360 deg with the caveat that there must be no other flashing beacons in the vicinity which might cause confusion.
