On the subject of trailers, why are they allowed to disguise the
mandatory reflective triangle in a trendy light cluster, so that
it is often impossible to distinguish it in daylight?

I can accept that it may be more important at night, but not to
the extent that it can be invisible otherwise.

Why do you need to see the reflective triangle during the day, apart
from in poor visibility (fog, heavy rain)? I presume it still reflects
properly (in order to comply with the law) so is there a reason that you
need to distinguish it from other parts of the rear of the trailer?

Is it to allow you to distinguish between the back of the trailer and
the back of the towing car? If so, I can't say I've ever thought of it
meaning "this is a trailer", just that its the standard reflector that
all vehicles have in addition to tail lights.

It is not particularly important on a trailer or caravan towed by a car,
as following drivers can distinguish easily, but it is helpful to
distinguish between and 7.5 tonner and an artic or a truck towing a trailer.
