Hello Kashi,

Thank you for using Apple Support Communities.

The light that you are seeing is most likely coming from the TrueDepth camera that is used with the Face ID technology. Take a look at this support article for more information on FaceID technology: About Face ID advanced technology​

The 'Safety' section has this information on what you are seeing:

When viewed through certain types of cameras, you may notice light output from the TrueDepth camera. This is expected as some cameras may detect infrared light. Some may also notice a faint light output from the TrueDepth camera when viewed in a very dark room. This is expected in extremely dark settings.


Best regards.
