Double check that the previous owner did not use 12 volt bulbs. You should be able to check with an ohmmeter, and if you can see the wattage of the bulb, Ohms×Watts would be around 150-200 for a 12V bulb, but only 35-50 for a 6V bulb. 6V bulbs have a lower resistance so they draw more current, to be able to make the same amount of light.
