Fog Light Replacement

Hi..I've a 2011 Gen3, came with aftermarket fog lights-they're more for show since they don't do much. But one is blinking...and I can't change just One bulb. There's about a dozen in each assembly. They'er LED. I was looking around to replace them a few years ago, never did. But I did some searching again, found 2 companies, they look great, but the products has NO ratings! Here's one..
Toyota Prius (10-16) Morimoto XB LED Fog Lights | LF220

So do I just take it to Toyota, have them fix the one (wiring?), or tell them to replace both to real OEM fog light assemblies. I've been messing with these front lights forever... lol
