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

 

I'm pretty sure these were aftermarket, because the dealer looked up my VIN, said the car came with no fog lights. But if it did, it's a single-bulb light. I looked up on autoparts.toyota.com and printed it out with the part #. The link above is everything. Just remove the old one, install the new, work the wires and that's it. It's one assembly. I may just have Toyota check the wiring, find out why it's flickering at times.
