Re: head lamps?
Petzal, black diamond, and the energizer, are the best bets for me. Red light is gooood.
I carry one every time I go out. One doesn't always know when we'll be staying late.
Several times I've left a small bike strobe going on the truck dash to help finding it later.
Generally I only carry one full size headlight, (but 3 fresh aaa's are stashed in the vest).
Also carry one key-chain light as a backup.
I also practice walking around in the dark a lot. But not in cougar country.
They tend to approach from behind, so keep rear looking radar on.
Don't want to be today's special.
Ultimately, it's not catching fish that satisfies, but knowing how.
