2004-2006 used little LEDs (also served as the robot status light) that nobody could see and made it very difficult to tell which alliance a team was on.

2006 also had flags. Occasionally one would take a direct hit from a Poof.

I want to say that before the rotating lights, teams used large pieces of red/blue material to mark alliances--I also want to say that it was laminated paper. But that was WAY back in 1999 or so, so my memory could be way off.
