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.
