Trailer light board, correct width?

[Boosted LS1]

I recently came across a 7ft wide boat trailer with a 4ft wide light board. Surely that can't be right. I'd have expected the correct board width to be 7ft. Is there a correct width or a place where I can find the legislation? I've looked on the net but most sources seem to stipulating the lighting requirements. thanks.

Try this :-

I searched for "width of trailer light board".

It looks like the light board itself is OK but the trailer needs :-
at least one red fog lamp.
White front reflectors.
White front markers/lights.

Used to be that the indicators were a max of 400mm in from the end of the trailer, with a 400mm minimun gap between. 4ft board on a 7ft trailer probably just works/fits.

Thanks. That's the sort of stuff I was finding. I would have expected there to be a requirement to have reflectors at the outer corners of the trailer.

Or by people who have bike racks on the back of their car and also have a trailer board.(Which is unusual in itself, given that most just block out their rear lights with their bikes and don't give a toss about what drivers behind can or cannot see)
