what size is yours Clive ??
Here's mine. You can just see the LED below the Trip reset button.
Now I call that neat, only a 5mm hole. It's just glued in from behind with silicone, the wire runs round under the trim, and the sealed heatsink electrics do dah is stuck with double sided tape to the side of the main frame spare.
I fitted a amp meter last week...works great @tu*
It has a digital read out as well as 3 lights on the
far right...
cheers...
