About Lexus Headlight Switch

Headlights rarely fail, but there are some instances when they don't activate because of a damaged Lexus headlight switch. Just like any other switch in your car, headlight switches open and close electrical circuits. A Lexus headlight switch is responsible for controlling the parking lights, driving lights, and the headlights. When electricity passes through the coil, a magnetic field is formed, pulling the magnet and causing the switch to close.
