LED Rear lights. Why do they need to pulse on and off?
I was following a car, with red LEDs. I found them so annoying. Every time I moved my eyes I could see pulsating lights. Why do they need to do this? They work on DC but every car so equipped that I follow gives a pulsing effect. I know they are more reliable than filament lamps. Have they ever given anyone epilepsy?
Yes they do flash at a high rate which looks continuous if I do not move my eyes. They are mainly on Lexus, Jags, BMW and other newer cars.
They do flash very fast. They need to do this to be able to be bright enough. Although you should not be able to see them flashing due to the high frequency.
However I have seen them seem to flash. It may be a combination of them and street lighting
This link explains why they are pulsed
