Got them from a guy called RPM 956. I actually found him on a highlander forum (2002 is my daily driver) claiming he has the best LEDs. I didn't beleive him at first but figured it was worth a try. I was suprised with how much better they were than other amazon LEDs I've tried. So recently hit him up to get bulbs for my 2012 Ram (Headlights, fogs, switchback front turns, tail lights, license plate and dome lights). He also has a 2 year warranty.

He did tell me I might need resistors for the tails, and bought a harness, but so far I haven't needed them. I think the canbus in your 2013 is different than my 2012 though so you might not have the same results.
