On ye olde (older than Accy) UK telly, 1960's shows with night scenes oddly are always dark enough so people can hide but bright enough to cast shadows and they can all see perfectly on cloudless 'nights', presumably, with the full moon up.
To be fair, this still happens in US-made films/TV to this very day. It's a full-on irrational irritation for me!
(Most commonly done when characters are chased across corn-fields. No, I don't know why this is so common in the US. )
