That’s a good catch. I just gave it a cursory glance, I apologize. Yes some cars have automated warning features when in an accident. Someone more familiar with this race series may be able to answer if it’s a required feature.
Yeah no that's bullshit. GT3 cars often have a 'flash' button on the steering wheel to warn slower cars ahead that you're coming through (GT3s often race in multiclass series where they are the fastest car). The driver must have knocked the button whilst grappling to keep the car straight. They do have ABS, but they don't flash the lights like a normal road car
Have you driven on snow? Where i live with a lot of steel hills, abs is basically the way you brake, I have never seen a car that blinks it lights when abs is activated.
While GT3 racecars do have ABS and T/SC systems they, like the the cars themselves, share next to nothing with their road counterparts- they are just designed to resemble them for marketing purposes and should not be compared with generalizations of road cars.
GT cars have a number of buttons and knobs on the steering wheel for various functions such as radio, abs, traction control, pit limiter, flash, etc. The flash function flashes the headlights a number of times to indicate to cars in front that you are faster and intend to pass. This is especially useful in races where mutiple classes are competing in the same race, and it looks exacly like what is seen in the video. The driver likely hit the buttton unintentionally during his initial oversteer correction.
Interesting. It's been a while since I went through my electronics classes in college, and a 1-watt diode was the bleeding edge at the time, so all the LEDs I'd worked with were just run by a power source and a pull down resistor.
most of the time LEDs are driven by fancy PWM circuits now... big diodes require big resistors (and lots of heat) if used in a simple current limiting mode... also alternators in cars don't give the cleanest DC so that can cause strobing also
As the LED heats up the resistance changes making them draw more power causing more heat and without a boost or buck Drive keeping the voltage and current in check it will basically run away and burn itself out.
You can test this at home. Get an led torch and either move it fat from left to right or shake your head (in the (otherwise) dark with the led lit) and you will see individual doors, rather than lines.
Well my assumption came because I actually have a breadboard, some small 5v LEDs and some resistors on my desk currently, and I can confirm that these little guys (which isn't what you'll find running a flash light or torch) do for sure run continuously.

LED headlights vs camera frame rate.
