H4 with Hi/Lo Beam
A Xenon bulb provides a single and constant light source. The H4 Hi/Lo beam effect is obtained, by moving the bulb forwards or retracting it backwards, when it receives the signal from your dip switch (Hi/Lo beam switch), this is done by means of a solenoid at at back of the bulb.
When the bulb is moved forward or backwards, it changes the actual point of focus within the reflector, thus changing the beam of light projected from your headlight reflector
