Hide Physical Lights

Hi, 

This might be super obvious, but I cant seem to figure it out... Is there a way to hide the large white dot that shows where youve placed a physical light? In the Stager pre-set demo, the physical light is not marked with a dot, but if you intereact with it, it then has that annoying dot in the way. 

Also, is there an option to hide any object or light from the camera but still have it cast glow on the surrounding environment? 

Thanks alot, 

A
