When I did mine I went with the simple 2 wire RED Datel.
It can still be read in the daylight without issue in most all circumstances.
I mounted mine on a shelf that I made similar to the ones that Richland Rick sells that mount on the front of the triple clamp. I also have a power outlet and heated grip switch there.
If you have an issue seeing it at some moment in the daylight hold your hand over it to block the sun and you'll be able to read it just fine.
