Its a HID system for H4 bulbs that utilises electromagnetic solenoid to push/pull the bulb/cutoff shield front or back to give low/high light.Hohoho, Veloc, it's true, and even my previous xenon lights burned a black mark in the reflector lens and the light beams are like firework scatters to all direction that caused dangerous glares to other road users. I have since reverted to halogen bulbs and the light beams are very focus now
Magnetic HID is a new term for me. What is that?
The normal non magnetic H4 HID will use HID for highlight and a small halogen bulb for low light which gives rubbish illumination. Its main purpose is just to change the colour of the lamps to pass road blocks. It doesn't really function to illuminate. Its weak.
