I65 DIPPED HEADLAMPS LOWERD AND NOT MOVING - Alfa - GT - eLearn

125000554 - I65 DIPPED HEADLAMPS LOWERD AND NOT MOVING

Both headlamps are lowered and not moving. Warning: Presence of high voltage (25kV) at the gas discharge bulb connector during the first 0.7 seconds after the dipped headlamps have been turned on. Do not switch on the dipped headlamps when the discharge lamp connector is not correctly connected. Do not disconnect the discharge bulb connector with the dipped headlamps switched on. Handle the discharge bulb with clean, cloth gloves and never touch the glass bulb with your fingers. Do not reverse the polarity of the supply line for the headlamps or else irreversible damage will be caused to the control unit.
