sfr's tenant is responsible for all inside and out multi's -- common areas are LL responsibility
my leases say T has inspected all switches, receptacles, outlets and bulbs at possession start and found all working properly. T is responsible for all maintain and replace not to exceed 60 watts and to return at surrender with like kind working.
you're right in saying most leases do not state. After a couple of instances where T have vacated and took bulbs with them,.....or left one working and the other six in the fixture burned out,.....I started putting that PP in the lease,.....including bulb replacement costs. LEDS have come down quite a lot,....but they're still serious money when you have to spend the time and money to be replacing 20 or 30 of them.
