That is a little strange. I would try jumping +12V to the switch from another source, ideally direct to the battery with an inline fuse. If that stops the flickering then you have a connection issue down stream, most likely at the breaker. You can use the same method to check each connection in the circuit path until you find the culprit.

I will try that . Interesting thought, I have been checking downstream FROM the rocker switch, not thinking the breaker to the switch maybe culprit. I'll let you know what I come up .
Thank you for input.

Are they regular bulb or LED? Regular.bulbs pull more amps. Could be a corrosion issue causing resistance after a bit it heats up and starts the issue.

Easy to order some led bulbs on Amazon. They draw so little current your flickering issue may go away.
