Still, there is a valid point relevant to our small discussion.
Landing lights certainly illuminate ground because thay are designed to do so. Explicitly, at 3 to 7 deg pitch (FCOM 3.03.22 p1) typical for landing and flare attitude. It is only natural to observe that during taxi, take-off, and landing roll they seem to pointlessly aim downwards.

However, that is EXACTLY what you need for landing. On the other hand, TO light is constructed differently, and hence the conclusion that it is pretty much useless in this phase.
