The picture of a night fighting Makarov does smell like Horsesense.However,I believe he would have coated the bulb with a strong smelling effluent(horsescent?) to disable an attacker and thus save ammunition,and a hand crank to save on batteries-a real stroke of Horsescents..
It's not as bad as it looks - even if the hamster is likely asleep when you're startled by a night-time burglary, you just fire a couple times and he'll wake up pronto. Then you'll have all the light you need.
Caution: elderly hamsters may suffer cardiac arrest from muzzle blast.
