HID Flicker Even After Relay Installed

Hey all, not sure if this is the right place but here goes;

As the titles says installed the HID kits correctly using relays on both sides of course. For the first ten minutes or so the light output was steady but then both started flickering on and off.

I'm a noob to installing these kits so bare with me. What can I do to prevent this? I removed both kits for now until I can find a resolution for this issue. Any help or advise you can offer will be greatly appreciated.

PS I had very loud buzzing coming from the relay as well. Would love to fix this also.
