A standard indicator bulb is 21W. In a 6V system the current will be 3.5A per bulb, so 7A per side for the front and rear. Flexible cables are usually sold as something like 32/02 being 32 strands of 0.2 copper wire, this example would be amount to nominal 1sq mm cable which would be generous for your indicators. I would fit a fuse but otherwise wire them directly; i.e. not via the ignition as otherwise using a hazard light facility is restricted.
