Nope, Tony's right, Observers do have a light function. In Ch37, during the Hide-and-Seek test, after Quant destroys one of the Lighthouses leaving Ship Leesoo in the dark, Leesoo noted that both his Observer and the other Lighthouse were too far away; this alone implies that Observers have a light function. Also, in Ch39 you can both of Leesoo's Observers emitting light.

Another example would be at the end of V2Ch55 where we see Team FUG completing their 29th Floor test; Yuto has two personalised Observers floating beside her. Finally in V2Ch63 in the One Shot, One Opportunity game when engages Vespa we can see her two personalised Observers again and as well as them, we see Leesoo with two of his own personalised Observers.
