I was finally able to upgrade my foglights. I used the bumper removal guide posted earlier in this thread. Post facelift instructions are a little different. Only difference is that there are a few extra 10mm screws beneath bumper to remove. I didn’t have to remove the harness that connects to the bumper. Instead, I left it attached and still was able to remove my old foglights and pop the new ones on there.
I also found out which foglights to buy on eBay for those that are looking to do this upgrade.
Make sure you buy a foglight that has both the led bar, cornering light and the square foglight lens. The most important thing is to make sure the square foglight has a visible clear lens in the housing as opposed to a blacked out lens. Blacked out lens don’t have the foglight function. There are a lot of foglights for sale that are just cornering lights; meaning only the led bar and cornering lights work. Please see my attached picture.
You will still have to program at your local Tesla dealership to enable the foglight function.
Any foglight you purchase on eBay that has the led bar, will be plug and play. Pre and post facelifts all use the same foglight mount.
