I once got pulled over because my plate was off to the side. Officer ran my name for warrants and came back clean (of course) when I told him it was covering up a hole from an accident of a previous owner, he said since I made up the light bracket thing, I could figure a way to mount the plate in the middle.
I took the lights off after that. Never actually wired up the lights. Never moved the plate, never got pulled over for that again.
4 more days.
