Light with Flare not working

I have a light with a flare - supposed to look like the sun. This works great as a standalone scene, but when I bring it into a larger scene the flare does not seem to work. Needless to say, I have little to no experience with this features so any suggestions would be greatly appreciated!

Change the settings of the flare, the rotation of the tranform holding that component, the light in your case. Make sure the camera has a flare layer (which it should). Check if the asset used as the flare is correct.
