I originally fitted my spot lights to the badge bar which worked quite well with very little vibration as the I got the BMW lights made of stainless steel which are identical to the chrome Morgan version but don't rust. I got the Stafford Vehicle Components. If you're interested I can email a pic of the brackets to you and I don't mind sending them to you.
I've just changed to using the Librands 3 point brackets that have been fixed to the bodywork. I got them drilled and suitably protected the holes and it allows the lights to sit further back of which I prefer the appearance.
