Im a naughty boy. I have them fitted on my black 96 car.
No doubt I will get caught one day. I have the proper ones in the car, just in case.
I've noticed you're not alone in carrying a spare set of legal plates from others comments, but surely if you were stopped and challenged and you pull out the legal plate, "sorry officer I've got these" it just shows you know you're normally running with illegal plates ??
ps, not picking on you Bonesie, just an observation
