My house has a house number sign on the wall next to the garage. I
never knew it can light up at night until I recently opened it up and
saw 2 bulb holders with 2 bulbs, and 2 wire nuts. The 2 bulbs are not
working at this time but I am not sure if they are both bad or I need
to connect the 2 wire nuts to some light sensor devices to enable the
bulbs to light up at dusk. Can someone take a look and advise? The
bulbs are 18V and 6W. I tried to look for them everywhere but they are
really hard to find. Can I use a 110V, 6W bulb instead?
The wire nuts have a black, a white, and 2 small low voltage cables
connected to them. What are these for?

I have the same type sign - _low voltage bulbs_. They have never
blown or failed (12 years). It is possible the wire nuts have
corroded, so the connections need to be cleaned and reconnected with
new wire nuts. Then try the bulbs again.

Check for a transformer inside the garage. Any markings on the black /
white wires that indicate voltage?

Certainly, test the wires for voltage and be sure they are low
voltage. A local electrical supply can get the bulbs for you?

I'm not an electrician, so take my advise with a grain of salt.
