I have a led security light with a pir sensor, and the knobs? which are
used to adjust time , sensor and lux are a bit confusing as to which end
is the setting end.

The 3 knobs are all the same shape, and when you look at them or just
one from the side view, it is tapered and has a small dimple in the high
end. All 3 knobs turn through 360 degrees, as it is a bit like guesswork
at the moment, but I'd prefer to take the guess work out of it when
setting the light up correctly.

Any ideas anyone?

Have a closer look. Mine have function and direction of rotation marked in
lightly embossed black markings on a black background next to the black
knobs! In poor light even with my reading glasses I can't see them.

Same here.

But IME there's always been a certain logic to the direction. Clockwise
= more (time, sensitivity, lux), anti-clockwise = less. Having said that
the clockwise/anticlockwise brain cells get confused when I'm reaching
round the back, which sort of mirror-images everything, so I imagine
myself behind the light while doing it, IYSWIM.

Ok, next to each knob, there is a part circular tapered embossed marking
when looking at it from the underside front, or upside down, the
embossed circular taper looks to be on the front right side and tapers
or narrows, from the front to the right side.

Again each knob has a small dimple at one end, so is that the denoted
setting end. In other words if the knob has the dimple next to the part
circular embossed taper, is that the setting end. I suspect it is, but
am not sure.
