The new tutorial uses the boat light which should mean the in-game searchlights are not dimmed down to a pencil thin torch beam. Also got rid of the 'fireflies' halo effect on the beam - this looks great on a street lamp but not so good at the end of your gun barrel. I've added an extra line marked in purple which stops the game crashing when the gunlight gets shot out. If you decide to use gunlights in your mod remember to tick the night box in the environment settings for that mission or they won't work proper.
