In the planning for Operation Overlord (the Allied invasion of Normandy), No. 85 Group RAF was to be responsible for Night-fighter cover of the beachhead and bases in Normandy after D-Day, and was keen to have searchlight assistance in the same way as Fighter Command had in the UK.
In practice, most of this plan was never implemented, liaison with the US Army units around Cherbourg having proved problematical once they were on the ground.
