The rule states that a robot is required to carry the police light and that it has to be seen from 4 sides,
90 degrees apart. Would it be legal to use mirrors to reflect the lights?

Say you hide the light in a box with one side open, then use a system of mirror to reflect the light from
that one side of the box to four different direction that can be seen.

Would this be ok?

Does Small Parts carry suitable mirrors?

Can you protect them from being broken during the competition?

I have no idea whether FIRST would approve of the use of reflective surfaces for directing the light, but certainly one could polish a piece of aluminum plate to mirror reflectivity if one was so inclined.

No need to rely on Small Parts for that. But if you insist, see page 286 of catalog 20.

It would, however, be easier to simply find a spot where a hole in each side lets the light out...

Haha...

Why don't you just put a gyro on one mirror and have it use absolute possitioning and a little trig to reflect the light into the eyes of the judge at all times. Isn't that better than four sides?

(I knew that toy motor would be useful for something...)
