Waiting for video.
I can't visualize what you're talking about or why you'd add lights when they are already there....obviously missing something, here....lol.
Yeah, it's hard to explain over the computer!! Basically, if you stand behind your truck and look at your side mirrors, you will notice that the mirror housing isn't exactly angled at a 90 angle compared to the truck, so since I mounted the LED strips directly on the interior of the housing but in from the edge of the housing at about an inch in, the side portion of the LED's in the housing actually aims at the rear door! By putting that extra strip of LED on top of the other, you can actually see individual LED's now on the side and bottom! Basically, you now see the second layer of LED's on the side of the mirror, while seeing the first layer of LED's on the bottom, because of the angle of the mirror housing from the rear of the truck!
So hard to explain what I mean but hope that kinda helps out! But trust me, after taking my videos tonight of how everything looks, I do highly recommend 2 strips per housing! No overkill at all and very uniform, bright but not obnoxious!!

Gotta apoligize once again for the crappy video, my camera just doesn't like taking night pics of flashing lights!! lol
Video of the lights with only a single strip of LED's in each mirror:

Video of the mirror lights from inside of the truck:

Notice how the side of the mirrors is a bit more faint than the bottom on the first video but looks even with the bottom LED's in the second video? In the second video, you are seeing the bottom layer of led's on the bottom of the mirror while the sides of the mirror you are seeing the second layer of LED's because they sit out from first layer, giving you that uniform LED look on both sides from the rear of the truck!!
