I’ve watch your video and this is a long shot. Try and remove all flasher lamps from the top box, the sound is syncronised with the flashes.

Quoted from sparky672:

Hmmm... there are white bulbs that flash randomly and those are the flasher type light bulbs. There are also plain red bulbs that flash sequentially like a marquee in the outer box that are driven by a small flasher board. Which ones are you referring to?

The randomly flashing ones, not the marquee.
