Great tip, thanks Chris.
what about placing a switch? Do you know how find the main power line for the rear area and switch it? Is it close to the rear view mirror?

Or you could adjust the wiring to the rear lights so that they are powered by an alternate power source e.g. leisure battery/portable power
