There are several videos on YouTube showing the simple installation of a module that will flash the LED high mount stoplight several times very quickly, then about 5 times more slowly, then go to full on. I bought the module in the video on amazon for less than $7 shipped. I don't know how robust it is but so far after a couple of weeks, it works great. On my 2017 there was very little extra length in the OEM wiring harness, but the installation was still very simple. You can check out a video posted by someone else here:
