i have often heard the story told on my team about our 2001 bot.
they were having problems getting the robot to function properly (maybe drive train woe, i dunno, i wasn't on the team yet). when they looked, they noticed they had the red lens on the light. someone said "hey, red is for stop, green is for go. let's put the green light on." after this switch out, the robot moved.
we still joke about pulling out the old green lens and setting it atop the new light
