+// Light Replacer (LR)
+//
+// ABOUT THE DEVICE
+//
+// This is a device supposedly to be used by Janitors and Janitor Cyborgs which will
+// allow them to easily replace lights. This was mostly designed for Janitor Cyborgs since
+// they don't have hands or a way to replace lightbulbs.
+//
+// HOW IT WORKS
+//
+// You attack a light fixture with it, if the light fixture is broken it will replace the
+// light fixture with a working light; the broken light is then placed on the floor for the
+// user to then pickup with a trash bag. If it's empty then it will just place a light in the fixture.
+//
+// HOW TO REFILL THE DEVICE
+//
+// It will need to be manually refilled with glass.
+// If it's part of a robot module, it will charge when the Robot is inside a Recharge Station.
+//
+// EMAGGED FEATURES
+//
+// NOTICE: The Cyborg cannot use the emagged Light Replacer and the light's explosion was nerfed. It cannot create holes in the station anymore.
+//
+// I'm not sure everyone will react the emag's features so please say what your opinions are of it.
+//
+// When emagged it will rig every light it replaces, which will explode when the light is on.
+// This is VERY noticable, even the device's name changes when you emag it so if anyone
+// examines you when you're holding it in your hand, you will be discovered.
+// It will also be very obvious who is setting all these lights off, since only Janitor Borgs and Janitors have easy
+// access to them, and only one of them can emag their device.
+//
+// The explosion cannot insta-kill anyone with 30% or more health.
