This is something that depends on the situation. If they haven't passed inspection, try the team first. If they can show you something in the rules that permits the item in question, let the inspectors handle it. If they have (and they made a big modification recently), talk to the inspectors and make sure they have been reinspected.

An example: in AZ, during practice rounds, I saw a rookie robot glowing green--the exact green of the field lights. I was pretty sure they hadn't been inspected yet, so about half an hour later I went over and suggested they a) turn the lights off during the matches or b) take the lights off completely, and explained why. (I also volunteered to show them the rule if they wanted to see it.) They chose the second option.

Whatever you do, do it in graciously professional manner.
