Searchlight
Searchlights are only of use in missions where the Night Fighting scenario special rule is being used. They allow one enemy unit spotted by the vehicle to be fired at by any other friendly units that are in range and have a line of sight (the enemy unit has been illuminated by the vehicle's searchlight). However, a vehicle that uses a searchlight can be fired on by any enemy units in their next turn, as they can see the searchlight shining out of the dark.
