Not a multiple flicker. Happens once or twice a night, though randomly.
I'm not sure to change bulbs or if this is an electrical problem.
Before I take it to a garage, I wanted to research myself if possible.

Thanks!

Does it occur to both or only one side?
High or low beam?

I would suggest checkng the relays. If only low beam try swapping with the high to test.

Yes, I'm pretty sure the alarm isn't going off.

What do you think is the cause of my headlights "blinking"?

Swap the high and low beams relays and retest. It could be a failing relay.
