In this video, the turn signals come on when he hits the brake lights. So these are not from Hanshow. The Hanshow ones in their install video, if you go to the end of it, you will see the brake lights come on (5 squares per side) without the turn signals lighting up in a pair as well. Chinese spec has only one reverse white side, the right side, while the left is for fog. EU and USA/North America spec have both white led s on both sides.
So in this video, the guy cheaped out to get a less than idea set. I know he says he's getting a cable to fix it, but I don't like not having the two reverse light sides.
