I voted yes, but only because - again - there's no "not really afraid of darkness, but definitely afraid of what can be hiding in it".
I'm fine with a lot of dark situations and places, when they can be reasonably trusted to be safe, but some - like being home alone in a house that make odd noises, or dealing with a flat tyre on a deserted-SEEMING country road on a moonless night, can be incredibly creepy... leading to at least a low level light (5w CFL or whatever) being left on in the hallway/landing for mental comfort's sake, and always keeping a couple of torches in the car so there's one spare for shining around the surroundings (or into an unexpected companion's eyes) without disturbing the one shining towards what you're working on. Or in case that one breaks and the car battery goes flat, leaving you completely isolated and at the mercy of ... whatever the hell it was just made THAT noise...
Can't help it, my genes have been passed down from tree dwelling, diurnal apes for whom such paranoia was a worthwhile defense system, and I have an overactive imagination / subconcious that likes to torture me with the ideas of various things seen/read in the (very few!) horror movies or literature I've allowed myself to experience. Like, I know it's not real (in the same way that the audience watching when I have to go out on stage isn't about to either boo loudly or rush forwards and attack), and I can tough it out if necessary, but the ol' limbic system doesn't give a crap about that. For a couple pounds a year equivalent in electricity and bulb replacement (or torch/battery purchases), it's worth it for the reduction in involuntary cortisone production.
Bizarrely, camping out in a field on the welsh coast, where there's arguably a lot more real danger, and traipsing about to/from pub, toilet block, seafront, tent by nothing more than the few photons my scotopic vision can scrape out of the patchy starlight? NO worries. Maybe it's just a very specific flavour of claustrophobia?
