The LEDs are pre-bent, so mount the LEDs on the component side.
There should be a photo in the Assembly PDF guide on how it should look.
If mounted horizontally, you want your LED colors to be
GRN-GRN-GRN-YLW-RED
.. and of course, the jumper soldered on the HORZ holes.

2)I want to orient the VUs vertically. What do the Vertical/Horizontal headers do exactly? Isn't flipping the board enough?
If mounted vertically, yeah, I guess you can flip the VU meter board upside down. (Yeah, that's easier. )
or you can solder the jumper on the VERT holes and mount the LED colors as
RED-YLW-GRN-GRN-GRN
The original reason why I have the HORZ and VERT jumpers was because I originally planned the VU meter to mate with my Mini-IO PCB. I can't flip the board upside down because it will interfere with the switches and jacks.
