The '''Combine Emitter'''Its model name 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. In the parts of the Citadel visited during ''Half-Life 2 Episode One'', they are seen used in a great extent. The devices 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==
As holders, Emitters can also be seen holding idle City Scanners in the ''Half-Life 2 Deathmatch'' map ''Underpass''. There they do not emit any light.
