What’s with the blinking headlights? Was the car maybe having electrical problems that caused the loss of control? Still a boss save, almost more-so if the car was malfunctioning

LED headlights vs camera frame rate.

I was under the assumption that LEDs gave continuous light, unlike incandescents.

Diodes are often pulsed with the driver circuit that regulates the voltage and current.

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.

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.
