It depends on the amperage that the light needs. One of the new style, LED bulbs needs only a small fraction of what a large 12 volt spotlight needs. It is not unusual to see a headlight bulb rated at 4 to 5 amps. Since a typical home light needs no more than a little over one amp, you are putting a lot more though the switch than it normally is made for.
A smaller bulb, like those for an interior light or tail light in a car is fine. The more bulbs on a circuit, the more amps it will take. Take the total wattage of all the bulbs and divide by 12 to get the amperage. Note that an automobile actually has over 13 volts, even though we call it 12 volts, but that is not a big enough consideration at this point.
Get a switch that is rated at over the total amperage.
Bottom line, one interior light bulb on a 120 volt rated home lighting switch is fine, but multiple headlights are not. You need to do the calculation for anything in between that.
The amperage rating of the switch is stamped on the metal and is listed on the box that it comes in. (ex...15A 120V)
To convert low voltage lights (e.g. 12 volts) to wattage equivalent to 110 volt lights, you would divide the voltage by 10. For example, 50 watts in a 110 volt system would be equivalent to a 5 watt bulb in a 12 volt system.
There is no need to convert a 110-volt outlet to 115 volts as they are essentially the same. The slight variation is within the normal tolerance range for electrical systems. If you need to use a device that requires 115 volts, you can safely plug it into a 110-volt outlet without the need for an adapter.
If you want mood lighting just connect it as is, the brightness of the bulbs will be half. If you want full brightness change the bulbs to 120 volt with bulbs of the same wattage as the 220 volt bulbs.
To convert 24 volt trailer lights to 12 volt, you will need to install a voltage regulator or resistor in the circuit to reduce the voltage to 12 volts. Alternatively, you can also replace the 24 volt lights with 12 volt lights designed for trailers.
To wire a 230 volt contactor with a 110 volt coil, you need to connect the 110 volt power supply to one terminal of the coil and the neutral wire to the other terminal of the coil. Ensure that the contactor is rated for use with a 110 volt control circuit. Additionally, verify the wiring diagram provided with the contactor for proper connection details.

NO
No, you can not hook up a 12-110 volt inverter to a house socket.
No conversion needed. These are nominal voltages which range from 110 to 120 volts. It will operate fine on the outlet.

12 volt
Purchase a power inverter.
Use a voltage devider or a transformer.
I hope not, it'll cook the 12 volt DC system.
If you want mood lighting just connect it as is, the brightness of the bulbs will be half. If you want full brightness change the bulbs to 120 volt with bulbs of the same wattage as the 220 volt bulbs.
It can be done with 90% efficiency.
