Thought I'd further update this as I did a bit more work today....
Was looking like this:
My issues were that firstly the 130 and 150 were bleeding a little white light (small niggle) but also, they were overall quite dull even with two types of LED bulbs used. Plus, the top of the dials were just too dull!
So I fixed the 130/150 issue and got some extra LED smd panels and rewired things myself. The result is a lot brighter and a more even spread light. The photos, again, don't give the real life effect as its overly glared up and the red looks orange, it is bold red.
All I need to do now is apply a bit more frosted vinyl to the back to diffuse the light a little more as one of the LED panels sits a little closer to the dials and so can be seen.
This is the view from the drivers seat:
I'm much happier now and with a little more tweaking, will be perfect!
