The reason for this sound, which is produced by the proofreader of headlamps, is caused by the excessive amount of factory grease in the regulator, which causes the contact to disappear. To solve the problem, first thing you need to pull out a driver's license is to open up, pull up. Next, you need to put the hand in the hole, locate the governor slot, and detach it. Then we need to put pressure on the control unit and pull it out. The controller unit needs to be disassembled and removed from it, clean up the contacts.
After the assembly is assembled, it is recommended to immediately check whether the adjustment wheel is rotated easily. If there is a problem, the governor assembly is not properly assembled.
