Nope
The Console detect the light, and if its off the game will stop. Its like convering the Wiimote tip.
And also, I really dont want sticky glue on my controllers because of bad design.
but it don't do that since PS4 don't have a camera built-in.
The light bar was most likely there when Sony was considering having a camera with every PS4, but now they dropped that idea so the light bar on the DS4 controller is really completely useless and Sony need to just redesign the controller and remove the light bar.
