This does seem to be a frequent problem area doesn't it? I fused mine inline
then moved on to one of those neat 7 fuse boxes that'll go right onto the
bulkhead in place of the original.
Peace of mind? Maybe. More peace of mind? Certainly.

Hi
This happened to me too a couple of years ago. Shortly after switching the
lights on smoke was let out of the cable loom. It turned out to be the red
cable that goes from the the light switch to a junction just under the fuse
box. This is the cable that feeds the side lights, aka parking lights. Upon
investigation the only thing I could find was that there seemed to be a
shortcut in the left rear light bulb. And as this circuit is not fused the
part that carries the most current of it burned. That is the piece from the
light switch to the junction, that feeds 4 bulbs, while the other parts of
this circuit only feed one or two bulbs.
Luckily no other cables in the loom got affected by this, so I just replaced
that piece of the red cable.
