A couple quick questions first please ... why are you using a 12 volt lamp in a 6 volt system? Have you increased the system voltage? Simply replacing a 6 volt bulb with a 12 volt bulb will cause the 12 volt bulb to burn dim ... Some systems have electrical circuits that drop (decrease) the voltage to certain units (like lights). For instance, your car is a 12 volt system (actually 14 when alternator is operating) and that 12 volts can be reduced with resistors to supply only 6 of those volts to a light ... or other device. Simply replacing with a 12 volt lamp will cause it to burn dimmer. Sorry to answer with a question but, I am just curious ...
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.
A 13.5 volt bulb will burn less brightly but last longer.
If your supply voltage is 120 volts the impact of switching from a 145 volt lamp to a 130 volt lamp would be, the 130 volt bulb would not have the same lifetime as a lamp operating on 145 volts. The upside would be that the light output would be greater. This is based on both of the lamps having the same wattage rating.
That depends on the wiring, the light socket, switch(es) and any other equipment in the circuit. You should never use a bulb that is larger than the original circuit was designed for.
All you have to do is change the bulbs to 12 volts and supply the trailer with a 12 volt power source. If you leave the original 24 volt bulb in the trailer they will only glow at 1/2 of their rated wattage.
No.
Can you use a 120 volt bulb in a 130 volt socket?

no
Yes if it is a 12 volt DC bulb.
A 13.5 volt bulb will burn less brightly but last longer.
Yes, the voltage listed on the bulb is the nominal voltage and it will work perfectly on a 120 volt circuit.
yes the bulb will actually last longer
no , it will burn out
Yes, the two voltages are in the same range category.
Yes, in fact that is what a rough service bulb is rated at. The bulb used on a 120 volt system will have a reduced wattage output as to what it would be on 130 volts.
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.
