Has anyone tried a "missile lock" tone?

[Bill Becker]

Our OI has a pair of safety glasses with LEDs mounted in the upper perifial and tells the driver if he has to pivot right, left or is locked. I guess we haven't thought about how to put them on at the start of the match. I guess if we win auton and become backbot he should have time. If not the operator will have to do it for him. Do think it would be legal for the driver to change safety glasses at the beginning of operator control?
