Default Mazda3- Headlight pulse on downshift.

So, my sisters car is doing something that i do not understand. Also, dont know much about her car in general...

Anyways, its a 2013 Mazda 3, 6 speed tranny.
I drove it tonight to bowling league and noticed when i downshift coming to a stop or maintaining speed on a hill the headlights pulse. Dim, Go back to normal, Dim, go back to normal. Not a strobe, but maybe half second intervals.
Running the AC(for more power draw) made no change in the interval rate, or the lumen output of this pulse.

She says she's noticed it for awhile. So, its not new, and she has not recognized any other electrical quirks. The battery is new, Alternator is, assuming, Original.

Any ideas?
I doubt ill be digging into the car to diagnose, but if it turns out to be fairly common, then maybe I'd tackle it.

Thanks for any inputs!
