Turbinlights I believe they were called.
Some aircraft did carry them including the A-20 Havoc.
Would it be complicated to implement a searchlight effect on adequately equiped aircraft? It would be like an additional gun position, controlled by the pilot/co/pilot/gunner.
But perhaps you're right the graphics demand might be a little high.
my two cents.
Good topic by the way - minus the adolescent whine & cheese society.
