I have been seeing a lot of these light mods on the 2014+ 5th Gen 4Runners, but never on the earlier 5th gen models like mine (2013). Part of the issue is the grille diamonds are much smaller, so all the plug and play kits will not work. I decided to get some 3/4" smoked amber markers, and 3D printed some grille inserts to hold them, and also point them out straight since the grille is sloped back where I mounted them on the top row. I would prefer to some LEDs that aren't round, but it's a start I guess.
I am just now starting to look at options for upgrading my vehicle since my toyota warranty finally expired, so yes, I know it looks very stock up front.
