No and yes. A 120-volt plug-in timer connects the line voltage to the timer and to the switch that is operated by the timer, so you can't use it directly for a 12-volt light.
However, if you use the timer to supply power to a step-down transformer, you can run a 12-volt light off the transformer (that's how most low-voltage landscape lighting timers work). If you don't need much current, you could even plug a 12-volt AC adapter "wall wart" into the timer. Otherwise, you would have to open the timer and modify it so that the micro switch is completely isolated from the 120-volt supply and bring it out to connectors for a 12-volt supply. Make sure you know what you're doing and also don't exceed the current capacity of the switch.
If you want your bulbs to last longer then use 130 volt bulb on a 120 volt system. The light emitted by a 130 volt bulb, when comparing it to a 120 volt bulb, will be a bit dimmer.
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.
120 volt xenon bulbs are fully dimmable just like a regular incandescent bulbs, using regular old 120 volt dimmer switches.
Mine has a 25 watt 120 volt bulb in it.
'Voltage' is electromotive force, and the 'Watt' is a unit of power. You can plug a 240 watt appliance (light, toy, radio etc) into a 120 volt socket as long as the appliance is rated for 120 volt AC operation.

The conscience is no. There is a work about by using an intermediary relay coil rated at 120 volts to switch the 240 volt feeder line.
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
The output of a 120 volt dimmer switch will be an AC voltage so should not be used on a DC motor.
The closest I can think of is a headlight timer or a old style diesel shut down timer. The head light timer was available from aftermarket part stores. The diesel shut down timer I was buying from our local heavy truck parts supply shop.

The timer has to be multi-pole. The ballast must be connected to the load contacts of the timer. If the timer is a 120 Volt timer, the timer has to run on a 120V. circuit. Loads are loads, and as long as you have a multi-load timer you can hook up whatever you want. If the timer only works on a shared power source (load shares the timer supply) you will need to use a contactor on the load side or the timer.
Yes, the 130 volts you read on the bulb is just the maximum it will handle. It will work perfectly in a 120 volt circuit.
If the ballast of the HPS fixture has a 120 volt tap then, yes it can be plugged into a 120 volt receptacle.
the plastic part of the light switch should never show voltage especially if it's a 120 volt circuit. 240 volts is two 120 volt circuits the circuit might be connected to another circuit in the bathroom separating them will fix the voltage but you should also inspect and replace the switch.

Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
Yes, the 130 volts you read on the bulb is the maximum it will handle. It will work perfectly on a 120 volt circuit and will actually last longer than a standard 120 volt bulb.
