The are the rules of interest...

5.3.2.3 Robot Visibility
<R09> Robots must display their team number, sponsor and school names, and/or logos whenever the robot is on the field (including practice sessions). The judges, referees, and announcers must be able to easily identify robots by Team Number. Teams must display their Team Number in four locations at approximately 90-degree intervals around the side of the robot. The numerals must be at least 4 inches high, at least in 3/4 inch stroke width and in a contrasting color from its background. Team Numbers must be clearly visible from a distance of not less than 100 feet.
<R10> Robots must use the two Team Color LEDs provided at event registration to display their alliance color (red or blue). One Color LED must be mounted on each side of the robot such that their displayed color is visible from a distance of at least 100 feet. Instructions for connecting the Color LEDs are provided in the Innovation First Controller manual. The Robot Controller directly powers and controls the Team Color LEDs. The user has no control over the Team Color LEDs and no program ing is required.

As I told teams, if your name isn't on the robot, the announcer only has team number to go by. People in the stands doing strategy remember team names but not always team numbers. When it comes to alliance picks and hearing about your robot on the field wouldn't you rather have your team name, sponsor, school visible for the announcers?
