Lumen R2 blinking

Hi all,

Our BlueROV (heavy config) developed a new problem since our upgrade from standard BlueROV penetrators to BlueTrail Engineering quick connectors - blinking Lumen lights.

Problem first occured during our first sea testing (depth to 25 m), lights started blinking in stabilize mode at 25%.
We managed to reproduce same blinking issue at our testing pool with 50% gain full throttle, while holding the ROV.

Could there be any interference due to power cable (oscilations in power cables while stabilize mode works in sea, high power - current while at 50% gain full throttle)?
Lumen light cable and power cable at the end cap are very close, could it be because of that? Or maybe some internal wiring setup creates this problem?

Thanks in advance,
