Wayne,
I can speak to the way it was for the Whelen LEDs I put in my Twin. They were remove/replace drop ins that were FAA/PMA'd. This may or may not be true for whatever model you fly - best to read the fine print.
The Whelen tail beacon was under the same STC for the Whelen 1970 rotating beacon but with an updated list fit was an issue (see other posts on this one)
