I presume cars are made a economically as possible, so is it really the

thicker wires?

A failed LED in an array won't make much difference to the function of
the light, but a failed bulb, which is far more probable, will.

The modern system does not make connecting a trailer light socket easy!

I bought my car with manufacturer fitted fold-away tow bar and electrics.
