The low beam spread seems to stay the same and when I hit the high beam I hear a clunk like a solenoid moving and it allows the projector to spread higher, is there a shield moving to allow this or is the light moving in or out like the aftermarket dual beam HID bulb? and is the part on the back of the bulb the ignitor or is it a solenoid? sorry for so many questions but I'm curious how it works as I am thinking on upgrading it, i find the high beam not so great.
