Still got to get lights on there. If you handlebar mount the lights, the lights are above the bars and the computer will be catch all of the light... making it unreadable and casting a huge shadow in front of the bike.
Hence moving the lights to below the computer, to either side of where the camera is mounted, and slightly ahead of the bars.
There's no pretty way to mount computer + lights + camera... but tidying it all into a sane cockpit that provides a lot of functionality and keeps the bars clear does make the most sense.
An ASCII drawing of the front face-on would be:
==== <- Computer
\/ <- Computer mount
O  O <- Light, Camera, Light
------ <- Extender bar
This doesn't extend above the top of the bars, nor intrude into either of the spaces around the drops. Seems fairly tidy.
