Skybeacon has an ADS B design that is quite clever. https://www.uavionix.com/products/skybeacon/ The instructions say to mount it on the wingtip using the existing light socket. Then connect the red wire and black wire. The unit has an LED position light built in. And you are ready to go. Now maybe Im missing something. Wouldn't it be necessary to turn on your position lights to get the ADS B to have power? How is that going to pass certification? Seems kind of trivial, but I would think you are going to have to pull a wire also. I don't know how much of a deal breaker that is but... Also there are a myriad of position lights and I know mine has built in strobe, so they are going to have to have a lot of models.
