The '''Combine Emitter''' is a Combine device used as an indicator to any event, emitting a chosen light or sound. It can be placed on walls, elevators, or weapon holders.

*Combine Emitters can be found in Combine-controlled areas, such as City 17.
*The parts of the Citadel visited during ''Half-Life 2 Episode One'' make great use of Emitters.
*Emitters are seen with their light facing downwards or upwards.
*The light is colored differently depending on the situation
*When used as alarms, they blink a red light and emit sirens.
*Placed on an elevator, they are silent and emit a blinking yellow light to indicate that the elevator is moving.
*On weapon holders, they emit a green light and are also silent.

==Behind the scenes==
*Its name comes from its model name, "combine_emitter01.mdl".
*As holders, Emitters can also be seen holding idle City Scanners in the ''Half-Life 2 Deathmatch'' map dm_underpass. There they do not emit any light.
