no , no switchable light in the boot
so, consensus of opinion is
open boot
3 lights come on
after a long time they will switch off [ maybe whatever does that is the reason they won't switch on again ...on the pump maybe ?]
can someone try the effect of pressing in the 2 switches immediately
? does that turn off the lights ? it didn't when I tried it , but why not ?...that's the same as shutting the boot lid

; or maybe they are then supposed to go off after a pause like the interior lights ?
anybody tried taking off the boot lid lining ? is that easy ?...can't see how it is done ; maybe having a look at the wiring there is a good idea , could be there is a loose connection
thanks for your offering chaps , much appreciated
