The best way to stop hyper flashing which is the flickering you are referring to on your LED light bar is to add load resistors like the Diamond LED Light Bulb Load-Resistors - Qty 2 # DI34ZR. You do need make sure the load resistor is grounded properly to get the correct function. The LED lights don't draw as much power as incandescent lights so there are sometimes issues with this hyper flashing until a resistor is added to increase the amperage draw to resemble incandescent lights.

If you have turned off the light bar and removed fuses and it was still flashing, then you have some sort of a storage capacitor in your lights. There should be no power getting to the light bar, so you will need to contact the manufacturer of your light bar if the load resistor doesn't solve that issue. The load resistor will increase the draw needed for the light to function, so I recommend adding it after the fuses and switch.
