Thanks Peter, that is exactly the look and mine is Royal Ivory too. My lamps are the smaller mini oscars. Mine had overriders which I have removed and there never was a bumper so it has to be wing-fitted.
I decided in the end to have them fitted by BHM and they are using the brackets as suggested here by Aerotaff and they are wiring them into the existing connectors under the wing, presumably with a relay if required, again as suggested by Richard V6.
I'll post a pic when I get it back. Thanks to everyone for advice and comments.
