Yeah those are the ones I got. One thing I didn't like about them is that they black anodized aluminum housing fades over time. It wouldn't be a bad idea to hit them with a little rattle can black before install.
I found these small LED's online somewhere (can't remember where) that were designed as blinkers for motorcycles. I put two on each side of the bumper. One was tapped into the taillight/brake light and the second one (amber) was tapped into the blinkers.
