Thanks for that, I've already had a go at it. I managed to cobble as much info as I could before and went for 2 x T4.2 Neo wedge LEDs and 3 x T3 neo wedge. They all work fine, everything lights up
. I stupidly didn't take a 'before' pic, but basically all three icons in the middle of the three buttons were not illuminated, nor was the left side of the panel in general, but looks great now.
