I built a contraption that could hold 3 lights and believe me, when you have a lot of lights the cars pick you up quick and start moving over a lot earlier.
Looks like you have a sturdy setup - but is any of that getting in the way of a pannier? Those are all nice lights - but once you ride behind a Dinotte of Magic Shine you'll appreciate the limitatations of low-powered setups. You need more watts not more small lights
