Check your charging system, sounds like the amperage output is too low too for any additional loads.

I did that and my charging system is good but the problem is still there

Then you need to measure the amperage that the light is drawing and compare that too the amperage that the alternator is putting out and then buy an alternator that can handle the increased power demand. It just seem odd, most of those led light bars I have come across just don't draw that much power. Could there be a problem with the light itself?
