They're supposed to be reflective, so you could get pulled over during the day when they're not lit and get a ticket.
Shining the 'correct' color is only half their purpose. I have no idea what your actual chances of getting a ticket are, but its certainly not DOT spec, (or whatever Canadian rules there are).
Perhaps a nice 'bad cop no donut' sticker on the back window?
That should add to your cop bait...
