In new generation vehicles, an interior lighting that fades in and out has become a standard. In addition to providing visual effect and comfort, this feature also contributes to safety. Especially when getting into the vehicle in the dark, if the interior lighting turns off abruptly as soon as the door is closed, causes difficulty for the driver in inserting the ignition key. It takes the human eye a couple of seconds to adapt to transitions from dark to light and vice versa. In the case of lights fading in and out, human eye adapts to change much easier. ELO Courtesy Light Fade In/Fade Out Relay is produced to provide this additional comfort and safety.
Principle of Operation:
If the door is open, interior lighting is constantly on.
20 seconds after the door is closed, if the ignition is key not switched on, the lights fade out.
When the door is closed, if the ignition key is switched on immediately, the lights fade out without waiting for the 20 second duration.
When the ignition key is switched from on to off position, the lights fade in and 20 seconds later, they fade out.
