I just put on my new 20 inch light bar I bought off of amazon today (auxbeam) brand. When I hooked everything up and fired the light up it came on but flickered for about 15 seconds and then it ran normally but it still had a little flicker but nothing like on start up. The bar is 126 watts, and I am running about 20ft of 16ga wire. Do I have a bad light, bad wire. Bad ground ....?
