Guncam footage - why aren't those gunners doing anything?

Here is an interesting fact regarding tracers used in bombers and gunner positions.
There was a special tracer made solely for the purpose of the enemy being able to see them.
They were designated the M21 Headlight and were several times brighter than a normal tracer. Some versions even had holes on the side of the bullet so the tracer element would burn out the side and even more visible.
The idea was to distract or intimidate the enemy pilots.
