On my new boat & trailer, the lighting board ends up behind the raised drive - number plate obscured - so that would have to be changed.
Trailer regulations state number plate must be on the central line of the trailer.
I had always assumed that lighting board had to be after the last part of the boat .... i.e. in front of drive, so light, reflectors etc refer to all that follows.
Anybody know if this is an 'actual' requirement.
