Pretty much a beginners question. Have been watching a few Builder type
programmes (Holmes on Homes etc) they have battery drills which seem to
have a light on the front I can see you would (might) need a light for
screw head finding that sort of thing but these lights only seemed to be
"on" when the drill was turning. Why have a light that is "on" only
when the bit is turning?

Bad design? There's a laser line on my mitre saw which is similarly
annoying and only comes on when the blade is actually turning - which
seems a bit pointless (I'll get round to rewiring it with a switch at some
point)

Many of the battery drills have a light that is wired to the trigger. On
the better ones you can pull the trigger gently and turn the light on
without starting the drill. It probably omits the capability to switch
it on all the time since this would be easy to forget and a very
effective way of flattening a battery to the point of damage.

Needless to say if you are working under film lights etc you probably
don't require the light and just use the trigger just for the purposes
of turning the drill, and hence create the impression that it is locked
to operation of the drill even if that is not actually the case.
