ELI5: Why is it when we look over to a blinking object the first blink seems to take a lot longer?

When I look over at my blinker in my car it seems like it stays on for a longer period of time than it normally does. Why is that?

This phenomenon is more commonly noticed with clocks, and goes by the name of chronostasis. What's happening is your brain decides that what you're seeing while your eyes move over to the blinker is too blurred/dizzying and therefore decides to ignore it for your own good. Instead it replaces it with a copy of whatever your eyes eventually settle on. So if your blinker is normally on for 0.5 seconds and it takes your eyes 0.1 seconds to move, you actually perceive the blinker for 0.6 seconds (assuming you look at it just as it comes on). This process is called saccadic masking.
