Hardwired Dimmable Illumination

NOTE: The smart junction box (SJB) is also known as the generic electronic module (GEM).

When the parking lamps or the headlamps are on, the SJB monitors the input from the instrument panel dimmer switch. The SJB sends a pulse-width modulated (PWM) voltage to the dimmable switches and control components based on input received from the instrument panel dimmer switch.
