Just tap into the tail light circuit (brown wire), and Robert's your mother's brother....

A feed from either (closest) of the lights will be fine..

Connect one wire to the brown, & the other to white (earth return)
This is assuming the trailer is wired w/- standard trailer cable, and in accordance with the recognised standard..

Standard wiring diagram(s) can be found here

If you are doing it with LED lights ( perhaps you might be changing over from bulbs) then Supercheap have a set that includes the number plate light as part of the tail lights. Just move the number plate position to under the park light. This might be easier?

Thanks Carl, they're not LED but i was thinking about that anyway. Unfortunately the tail lights are on mounts outside the body of the trailer rather than on the tailgate so I don't think that will work, tho perhaps moving the tail lights might be the easiest solution. Iain

be careful if your are looking at moving the lights, there are regulations with regard to where the lights need to be mounted. you'd probably need to search the National Code of Practice for building light trailers to find out exactly what the legal requirements are in regard to this matter.
