I reckon that goes a long way.
Just have a look at the number of people on the road with wildly non-compliants stuff: trailers with no lights, missing lights, reg plates scrawled on a Cornflakes packet, never minds all those bikes on rear carriers that completely obscure reg plates and lights.
Compared to those, a decent lighting board on the A-frame is far less likely to attract attention even if not strictly correct. It also has the benefit of not needing to route the cable along the trailer which is handy.
