When a survivor has a flashlight, you see them waving around trying to blind you. This is easy to avoid by moving your head about.
When you get hit by a pallet, you do not have this option as the animation plays. You already have a penalty because you have been hit by a pallet and either have to break it or go round. If the survivor then has a flashlight you cannot avoid it because of the animation and the inability to move your head, you then get a double penalty.
Maybe give the killer the ability to look away during this time, or even just close the killers eyes so pallet drops and blinding does not happen together.
I know you could run Franklins, but then you lose a perk slot. Or to even the survivors side, give them a perk to pallet blind, that way it would even the playing field, because if a player wants to flashlight they have to give up a perk.
