I have put together a simple white LED bar on the bottom of the KX3. No holes,
it clips over the bottom thumbs screws. Runs off of 9 to 16 VDC @ 25 mA,
regulated by a LM7808. I have a schematic and pictures for those interested.
BTW the bar is a plastic DIP IC stick with a AL sheetmetal
I think, darn I hate that, that the correct answer is a dual band module for

devices. The ONLY point of concern is that the assembly surface
A couple of additional comments.
Sometimes, if the soldering isn't perfect, traces of the water soluible flux
