This is my first time to hear halogen headlights flickering.

Because most of auto headlights flickering from led.

Due to small electric current of led headlights, BCM of car is imcompatible with old circuits.

If car halogen headlights flickering, I suggest you’d better check watts of halogen bulbs.

I doubt wrong watts of halogen headlights in there.

For example, if your original halogen headlights are 55w-60w, but present one is 27w-35w then it makes halogen headlights flickering.

All of our our auto halogen headlights are all real watts, so you don’t worry about halogen headlights flickering.

This is only my idea. If you have any other different idea about halogen headlights flickering, please inform me quickly.
