If you notice abnormal headlight aiming, such as low/high beam too high into oncoming traffic, or high/low beams uneven or knob adjustment ineffective, the headlamp level sensor switch contacts or wiring have aged out. Properly functioning switch controls motor-adjusted headlight reflector angle to keep lighting within safe range under different loads. Fits Toyota Camry 2007-2016 (four-pin plug); OEM 84152-02050. Installation requires disconnecting the battery negative, ensure connector alignment and locking to avoid misconnection and loss of adjustment function.
