Are LEDs in modern streetlights usually pulsed?

Pulsed LED operation is very popular among LED devices, so I want to know if the street lights also apply this method for dimming.

Yes, PWM dimming technology is one of the most popular LED street light brightness control technologies. PWM technology uses a switching circuit to perform frequency modulation by controlling the ratio of the LED’s working time. This technology can achieve efficient brightness adjustment with a wide adjustment range, has less impact on the working life of the LED, and also has strong anti-interference ability. However, this technology requires the use of switching circuits. It may cause a certain amount of electromagnetic interference, and the problem of pulse noise needs to be improved.
