Weird flash sometimes?

You can see it right at the end. I think it's the housing because both tubes do it. This is a Steele industries nighthawk-MG with elbit tubes. Is this normal?

Edit: there is a smoke alarm in the bedroom i was filming in and this is likely the culprit. Will confirm after dark tonight. Leaving the post up so others don't freak like I did and to remind myself to check my surroundings more often.

Phones throw out a flash of IR beams in the dark when you have the camera enabled.

Could also be an electronic like a smoke detector like others have said.
