i fitted mine to the front of the no-plate light, i made a metal bracket and bent it so it came out in front of the light (because you could still see some white light from the back) i screwed the bracket to the top of the no-plate light with a m3 screw and sealed it so no water could get in
i fitted it so if plod do pull you over its 1 less thing for them to mention and it does'nt look out of place
