The reason that a side/tail/DRL light has to be turned off is due to the
poor design of light clusters which places the indicators very close to
other lights. I'm surprised our Construction and Use legislation didn't pick
up on this and mandate a separation between indicators and headlights/brake
lights/DRLs so the indicators can actually be *seen* in all situations.
But the *usability* of light clusters seems to take a back seat compared
with the *aesthetics* of "does the arrangements of lights look nice".
VWs used to put the indicator in the centre of a ring of brake light (or
maybe it's vice versa) which meant it was hard to discern the indicator when
the car was braking. And almost every car nowadays puts the front indicators
in the same housing as the headlights which means the indicator can't be
seen easily at night in an oncoming car.
I think the dimming of a DRL next to the indicator works well: it is often
the turning off of the DRL that I see before the flashing of the indicator.
And another thing... I wish it was mandated that all cars must have *two*
reversing lights (one at each side) and *two* foglights (one at each side)
rather than the common trend of a reversing light only on the left and a
foglight only on the right, which makes it very difficult to see the
road/hedge/wall behind you on one side when reversing at night, and prevents
cars behind being able to judge the width of your vehicle as they approach
it in fog. I tend to turn my fog light on when I'm reversing into a confined
space at night, so the walls/hedges on *both* sides of the car are lit up
(albeit with different coloured lights).
