A:

It's tricky to get 12V from a 6V system, although with a switched capacitor circuit it could be done. Then you'd have to rewire the lights to connect to the 12V output. I think you'd do much better to buy 6V automotive LED lights. I just googled and it does turn out that they're available from several outfits. One thing you should watch for is to get the right polarity, which matters for LEDs, unlike incandescents. Some old 6V cars used + to ground and - to hot, some used the more standard modern - to ground, + to hot. Both types of bulbs appear to be available.
