@capebud1 I’m assuming this is in FS24? The beacons are definitely working – but it has to be sufficiently dark.

It has been reported since the release of FS24, that the exterior lights are too dim in daylight. Here’s a link to the official forum discussing the problem. I’m guessing, that’s what causing problems for you.
Same thing with nav and strobe lights, with or without winglets, they’re also working – if it’s dark enough. At least for me.
