Tourist - the OP did ask about landing lights but this has now drifted into the 'other' lights'. BA will be religiously sticking the inboards and logo on and off at 10000ft +/-1 ft 'cos it's in the book and the landing lights with the gear as you say.

- thanks heavens for one bit of sense in your post.
I see TypeIV has been unable to answer the question.
As de facto says - turning on any gear mounted taxy light for landing or take-off is NOT a good idea.
