Triangular light problem

Hi there, I recently picked up this triangular prism shaped tank off Facebook marketplace, it came with this light. I wanted to see if any of you knew which light this was as some of the LEDs keep flickering which can be quite frustrating and I’m sure it causes a bit of stress for the fighting fish I have in there. Please could someone drop me a link to a new light or give me advice on how to stop this from happening. Thanks in advance -Ollie

Never seen anything like it. You could replace it with a normal aquarium LED light unit or a hanging LED spotlight.
