yes !
I have a real clue to what might be happening ..

it's a blockage or leakage of electrons !   blocakage very likely.
Juice ain't gettin' where it should..
including blown filaments.

but don't rush out and buy new bulbs..
test and diagnose first. Always that first.

I hope he'll learn how to use a basic 12 volt test light to look for the
presence of juice,
and also ground.

all a person needs is a 12 volt test light, and some jumper wires ..
and know who to test a bulb on a battery say ..
and know how to detect ground.
all super easy, elemental even.
