A few weeks ago I noticed the left fog light was missing in my 2016 Tundra. Actually, the plastic bracket had broken and it was inside the bumper cavity. The glass doesn't appear to have suffered any impact, but Toyota would not warranty it. Toyota wanted $65 for the parts and $85 labor to install it.
I searched eBay and found an entire OEM fog light kit complete with both lights, wiring harness, and switch for $45. I bought it. I can't swear it's OEM, but it appears to be exactly like the original.
It took me all of 20 minutes to replace it.
