Looking for help/ideas!!

My old Trakmaster has "single wire"(+ve) incandescent clearance lights. The EARTH is the metal body of the light and the earth return is the aluminium cladding of the caravan.
I'm sure anyone reading this will know this type of light and be familiar with their poor waterproofing,the intermittent nature of the lighting primarily due to poor earth contact and poor contact/tension/corrosion of the two metal prongs suppying power to the festoon globes.
I want to replace these lights with LED units but the LED units are two-wire lights with a dedicated earth wire.
I am looking for suggestions as to how to install/mount these lights - particularly how to connect the earth. There is no option to run new earth wiring to all the lights without stripping out the caravan walls.
My initial thoughts are to make "spacers" on which to mount the lamps with room in the profile of these spacers to make the earth connection to the caravan body.
Any thoughts welcome
