Can headlight bumps be taken off?

[Sad, little man]

I was wondering if those little points that are on almost all headlights that I assme are left over from the molding process can be taken off. I was thinking maybe cutting them down to just a bit above the level of the headlight itself, then wetsanding until it`s shiny and even. Would this work, or would I never be able to sand something as rough as a chopped off piece of plastic to a shine?

Whoops, I guess they stay then. It did occour to me after I posted that the tail lights don`t have them.
