You really want to keep the LED close to the IC. Running long wires between them can lead to issues. You could use regular through hole LEDs with this if you change the layout to allow for the legs to go through, or you can bend the legs and solder them as if they're SMD parts, just on the surface of the board instead of through it.
On the other hand, having SMD lights like I did means you can put the LED behind the map without needing to poke a hole. Might be nicer ...
