Quoted from PM_Jeremy:Found something that will work
amazon.com link »
The description is 8 inch fixture but the bulb used is a 6". You will need to modify it but it's cheaper than buying individual components.

I am just so grateful cad-kid that you went out of your way to help on this and suggest a product. There is no way I would have found that product.
Anyhow the product arrived from Amazon US and I stripped the outer body to devise a fit for the components to fit within the Hamms beer barrel light area:

I found that a section of cable duct worked really well as the component cradle:

I removed the switch & cable connectors (would not fit in space)

arranged for the cable (white) to be channelled through to the rear of the machine:

and all finished and working:

Just to recap when I bought this barrel I had not realised that certain US States at the time did not allow lit beer signs and I (damn it) got an unlit one which was hopeless. But thanks to cad-kid it is now converted to being lit and I trust it respects the original install on lit machines.
