Just also be carefull to not drain more current (by using bulbs higher than 55/65W) it can cause an overheating or in the worst case fire in the cables.
I can not imagine that Morgan uses more thicker cables than the standard bulbs used...would cost to much for a 42K€ car.
Also consider that the Headlight reflectors and Glass is only plastic
and could take damage due to the heat...
