What light does the demon eye connect to?

[DeJasper]

The demon eye connects to the position light (also known as the parking light). Below is the relevant introduction: Function: The demon eye is generally connected to the position light and used as a marker light. When the position light is turned on, the demon eye will light up along with it. It can also be connected to the daytime running lights, and will illuminate when the car is started. Another function is to use it as an ambient light. Some cars do not have a built-in ambient light position, so a demon eye can be placed in the footwell area to serve as a footwell light. Origin: The demon eye is a colloquial term for small LED lights, as they resemble the eyes of a demon. The earliest demon eyes were red, but later versions appeared in blue, purple, green, yellow, and other colors.
