These lights would have a narrow beam that travels a longer distance. As a bonus: possibly make a visible and infrared variant. Then add a parameter to cameras "seeIR". Infrared lasers would be invisible except when looking through an IR-capable camera.

Bring back json-defined lights

Closing as this can be done via a generic light now. Visibility can be toggled based on an animation, so you can make it visible if you're looking through your IR-camera on your helicopter, but not visible if you're a normal passenger.
