That is because the manufacturers don't want joe public doing any job,
instead they want over priced specialists to do it.
However the current drain of modern lights is one heck of a lot less than
a bulb and arguably, less likely to fail without the driver being alerted
via a snazzy dasboard icon.

I presume cars are made a economically as possible, so is it really the
case that a rear light unit with LEDs and driven by CAN bus, with two thin
wires for the power and two even thinner wires for CAN-H and CAN-L bus is
really cheaper to make than one with convention bulbs and much thicker
wires?

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