Quote - try positioning the point light just below it (zoom in and / or use front /side cameras).

An easier way to do that is to use Ockham's  "Snap to it" script.  It's great.  The link below has a link to the program as well as instructions of use, not that any are needed because it's super easy.  Pick your light and then the destination and accept.

Snap To It

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
