Just installed the VLEDs V3 Triton in my rear turn signals. I can't say enough good things based on my impressions so far. The free shipping was ridiculously fast and the entire kit just looks high quality. It made me really happy that I spent the extra money. It was an easy, clean install and they even threw in the dielectric grease and heat shrink tubing to waterproof the old light socket connection. It took a little bit of trial and error to figure out the right combination of hardware to fit the socket, but I ended up just using two of the short screws, spaced 180 degrees apart, and the thicker of the small-diameter gaskets and the fit is really solid. One took a little extra force to compress the gasket to get the screws to catch, but they both feel secure.
They are insanely bright. My first reaction was actually "are these TOO bright?".
Here's a video comparing the LED with the factory bulb:

I highly recommend this kit if you're going to upgrade your rear turn signals.
